The novel trimetal-binding P(N,N′)2-ligand bis(1,10-phenanthrolin-2-yl)phenylphosphine (L) has been synthesized and used to assemble near-infrared (NIR) emissive complexes. Reactions of L with either [Pt(cod)Cl2]/Cu+ or [Au(tht)Cl]/Cu+ systems selectively yielded the trinuclear complexes [PtCu2Cl2L2]2+ and [Au2Cu2Cl2L2]2+, isolated as their PF6− salts. Structural analysis confirms that the PtII and AuI centers are P-coordinated, while each CuI ion is chelated by a pair of phenanthroline arms. At 298 K, the Pt(II)-Cu(I) and Au(I)-Cu(I) complexes exhibit NIR luminescence with maxima at 820 and 810 nm, respectively, which is attributed to triplet (metals and halogen)-to-ligand charge transfer 3(M+M′+X)LCT character based on theoretical calculations. Notably, the Au(I)-Cu(I) complex demonstrated cytotoxicity against tumor MCF-7 cell line, with LC50 values of 16.6 ± 0.7 μM, approximately twice the potency of cisplatin.

This work presents the rational design of a direct S-scheme heterojunction, fabricated by ultrasonically decorating exfoliated g-C₃N₄ nanosheets with CdO nanoparticles. Comprehensive characterization (XRD, TEM, FTIR, XPS) verified the successful synthesis, controlled CdO crystallite size, and the critical formation of intimate interfacial CdN bonds. The composite's performance is significantly amplified by synergistic adsorption mechanisms, including π–π stacking H-bonding, coordinate bonding, and electrostatic interactions, which preconcentrate pollutant molecules at the active sites to directly facilitate the subsequent degradation. The optimized photocatalyst exhibits dramatically boosted performance, achieving a pseudo-first-order rate constant of 0.0181 min−1 for tetracycline (TC) degradation, which is 4.2 times greater than that of pristine g-C₃N₄. Crucially, it demonstrates robust practical utility by effectively degrading TC in the presence of common aquatic interferents, such as inorganic ions and humic acid; its efficacy is further amplified by the synergistic addition of H₂O₂ as an electron scavenger. A concerted mechanistic investigation provides definitive evidence for the S-scheme pathway: Mott–Schottky and DRS analyses established the requisite band alignment, while XPS revealed a negative binding energy shift in g-C₃N₄, directly proving electron transfer and the creation of an internal electric field (IEF). Consequently, photoelectrochemical and photoluminescence studies demonstrated profoundly enhanced charge separation efficiency and near-complete quenching of radiative recombination. Radical trapping experiments identified •O₂− as the primary active species, validating the proposed S-scheme charge transfer mechanism.

The main challenge for decomposition and removing water contaminants using semiconductor-based photocatalysis is the efficient separation of charge carriers. In this research contribution, we rationally developed a dual piezoelectric-semiconducting heterostructure photocatalyst, composed of a mesoporous step-scheme (S-scheme) of AgVO3/BaTiO3, to synergistically promote charge carrier separation and kinetic rates for the highly efficient elimination of tetracycline by synergistic impacts under stirring and visible light exposure. The optical absorption examinations demonstrated that the AgVO3/BaTiO3 composites unveiled outstanding abilities to absorb and utilize light energy in the region of the visible spectrum. Additionally, PL and photocurrent evaluations verified that the AgVO3/BaTiO3 hybrids had the best capacities to spatially separate the charge carriers. The alteration in binding energy values within the AgVO3/BaTiO3 compared to pure samples additionally endorsed the directional flow of electrons from BaTiO3 to AgVO3 whenever there was no illumination, which implied that charges move in response to the S-scheme model when subjected to irradiation. Responding to the decomposition evaluations, the piezo-photocatalytic capacity was substantially enhanced by the most appropriate concentration of AgVO3 (15 wt%). This implies that sewage treatment might benefit from these heterostructures. After only 60 min of encountering visible illumination and stirring, tetracycline was entirely (100%) degraded over the 15 wt% AgVO3/BaTiO3 hybrid. This proceeded at an overall degradation rate of 2.4872 μmol min−1, which was 39.2-fold more efficient than the degradation rate achieved by pure BaTiO3 (0.0635 μmol min−1). Meanwhile, the 15 wt% AgVO3/BaTiO3 hybrid showcased superb stability and durability, signifying that this heterostructure material might be utilized over and over and endure for an extended duration. The simultaneous impact of the stir-generated piezoelectric field and the interfacial electric field substantially enhanced the charges' spatial separation and directional flux of the charges, which efficiently degraded and eliminated tetracycline. The research presented here shares crucial understandings and perspectives concerning the feasible design of innovative heterostructures with superior piezo-photocatalytic functionality to sustainably alleviate water contamination issues.
利用半导体光催化分解和去除水污染物的主要挑战是有效分离载流子。在本研究中,我们合理地开发了一种双压电-半导体异质结构光催化剂,由AgVO3/BaTiO3的介孔步进结构(S-scheme)组成,在搅拌和可见光照射下,通过协同作用促进载流子分离和动力学速率,从而高效地消除四环素。光吸收测试表明,AgVO3/BaTiO3复合材料在可见光光谱区域具有出色的吸收和利用光能的能力。此外,PL和光电流评价验证了AgVO3/BaTiO3杂化材料具有最佳的空间分离载流子的能力。与纯样品相比,AgVO3/BaTiO3内部结合能值的变化也支持了电子在没有光照的情况下从BaTiO3向AgVO3的定向流动,这意味着电荷在辐照下响应s方案模型移动。根据分解评价,最合适的AgVO3浓度(15 wt%)大大提高了压电光催化能力。这意味着污水处理可能受益于这些异质结构。经过60分钟的光照和搅拌,四环素在15wt % AgVO3/BaTiO3杂交种上完全(100%)降解。总降解率为2.4872 μmol min - 1,是纯BaTiO3 (0.0635 μmol min - 1)降解效率的39.2倍。同时,15wt %的AgVO3/BaTiO3杂化材料显示出极好的稳定性和耐久性,这表明这种异质结构材料可以反复使用,并持续使用更长时间。搅拌产生的压电场和界面电场的同时作用大大增强了电荷的空间分离和方向通量,有效地降解和消除了四环素。本文提出的研究成果分享了对创新异质结构的可行性设计的重要理解和观点,这些异质结构具有优越的压电光催化功能,可以持续缓解水污染问题。

In this study, alpha iron oxide nanoparticles (α-Fe₂O₃ NPs), magnesium oxide nanoparticles (MgO NPs), and iron oxide/magnesium oxide nanocomposites (Fe₂O₃/MgO NCs) were used for the antimicrobial activity. The hydrothermal approach was used to synthesize the samples (α-Fe₂O₃ NPs, MgO NPs, and Fe₂O₃/MgO NCs). The superhydrophobic surfaces of α-Fe₂O₃/MgO NCs were prepared by the spraying-coated sheets method with molar ratios (x = 0.01, 0.05, 0.1, and 0.2). The samples were characterized by XRD patterns, Raman analysis, FESEM images, EDX analysis, and FTIR spectrum. XRD patterns show that the average crystal sizes of the samples are 9, 25, and 42 nm, respectively. FE-SEM images of samples reveal the formation of worm-like nanoparticles with an approximate length between 100 and 120 nm, respectively. The EDX analysis indicated the presence of MgO and FeO NPs with high purity and uniform size and shape. The strong absorption peaks of the samples were 481, 431, and 574 cm−1, respectively, as determined by the FTIR spectrum. Paper impregnated with α-Fe₂O₃/MgO NCs had its contact angle with a water droplet on its surface studied and compared. Coated sheets with molar ratios (x = 0.01, 0.05, 0.1, and 0.2) have contact angles of 153.9°, 154.2°, 155.6°, and 159.4°, respectively; this indicates that all four samples are quite hydrophobic. Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidemidis) had inhibitory zones that were 13.00 to 18.00 mm, 12 to 25 mm, and 8.00 to 10 mm in size, respectively, according to this study. Escherichia coli and Klebsiella pneumoniae were gram-negative bacteria, measuring 10.00 to 24.00 mm, 14.00 to 28.00 mm, and 6.00 to 10 mm, respectively. Inhibition zone diameters (IZDs) for fungi were correspondingly 12.00 mm, 10.00 mm, and 8.00 mm. This study examines a recently reported combination of samples with superhydrophobic surfaces using the spray method for antibacterial activity.

The coexistence of heavy metals and synthetic dyes in water systems necessitates multifunctional platforms for the simultaneous detection and degradation of these pollutants. Zeolitic Imidazole Frameworks (ZIFs) post-modification with organic ligands has gained significant attention for environmental applications. In this regard, a terpyridine-functionalized ZIF framework (ZATpy) was synthesized via post-synthetic grafting to introduce the terpyridine ligand (Tpy) on the ZIF-8 framework. Unlike most MOF sensors using coordinated ligands or single-function designs, ZATpy features covalently attached uncoordinated terpyridine sites offering direct metal-binding access and enabling both ultra-sensitive Cu(II) sensing and efficient photocatalysis in a single robust platform. UV–Vis spectroscopy confirmed high selectivity of Cu (II) recognition with optimal response in the neutral pH (5–7) range, minimally affected by competing ions with a limit of detection (LOD) of 0.131 μM. Notably, ZATpy retained its Cu(II) sensing ability in complex real water matrices, including Yamuna River water, Ganga River water, seawater, and tap water. Furthermore, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) validated Cu (II) capture efficiency under sensing conditions with 28.7% adsorption efficiency. Photocatalytic studies revealed excellent degradation of methyl red dye, with 94.4% degradation in 60 mins and good reusability. Computational studies also indicated favourable adsorption energetics for Cu (II) and π–π interactions with aromatic dye substrate. The integration of free ligand functionality onto the porous ZIF surface enables concurrent ion recognition and charge-guided photo-catalysis, offering a viable approach for water purification.

Phytochemically-derived metal and metal oxide nanocomposites (NCs) represent a pivotal advancement in sustainable nanomaterial synthesis. The core novelty of this review lies in proposing a predictive synthesis-structure-activity framework that systematically transitions green synthesis from an empirical methodology to a rational design paradigm. This analysis critically correlates phytochemical composition with precise control over NCs morphology, crystallinity, and surface properties, which in turn govern functional outcomes. The multifunctional bioactivity of these NCs, spanning antimicrobial, anticancer, antioxidant and regenerative applications, is examined with emphasis on their underlying synergistic mechanisms. These include phytochemical-metal interplay that modulates cellular internalisation, reactive oxygen species (ROS) generation and intracellular signalling pathways. Current limitations, such as reproducibility, toxicity and regulatory challenges, are addressed alongside prospects for biomedical and environmental applications. This review establishes a pioneering synthesis structure and activity framework that meticulously unpacks the green synthesis and multifunctional behaviour of plant-derived metal and metal oxide nanocomposites.

Sunset yellow (SY) is a widely used artificial food coloring that can pose health risks when consumed in excess. In this study, a fluorescent sensor for the quantitative analysis of SY content in complex foods was reported. Using ammonium fluoride and sorbic acid as precursors, fluorine-doped carbon quantum dots (F-CDs) were synthesized via solvothermal method. The prepared F-CDs were characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The results revealed that F-CDs had a uniform morphology and fluorine-rich structure, with an average particle size of 2.15 nm. In addition, we found that F-CDs exhibited excellent selectivity for SY, mainly due to the fluorescence quenching effect of SY on F-CDs. Therefore, a fluorescent sensor based on F-CDs was constructed with a linear detection range of 0.010–75 μM (R2 = 0.997) and a detection limit of 30 nM. The sensor's practical applicability was demonstrated by analyzing of SY in hard candy, tangerine peel sugar, peach jelly, beer, and bread, with recoveries of 92.1%–115% and RSDs of 1.0–4.8%. What's more, the fluorescence detection results were closely related to the HPLC-DAD validation results (relative deviation ≤0.17), highlighting the accuracy of the method. F-CD-based fluorescence detection platforms offer the advantages of simplicity, sensitivity, and reliability, providing a promising tool for routine SY monitoring in food safety applications.

Therefore, a fluorescent sensor based on F-CDs was constructed with a linear detection range of 0.010–75 μM (<em>R</em><sup>2</sup> = 0.997) and a detection limit of 30 nM. The sensor's practical applicability was demonstrated by analyzing of SY in hard candy, tangerine peel sugar, peach jelly, beer, and bread, with recoveries of 92.1%–115% and RSDs of 1.0–4.8%. What's more, the fluorescence detection results were closely related to the HPLC-DAD validation results (relative deviation ≤0.17), highlighting the accuracy of the method. F-CD-based fluorescence detection platforms offer the advantages of simplicity, sensitivity, and reliability, providing a promising tool for routine SY monitoring in food safety applications.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"186 ","pages":"Article 116221"},"PeriodicalIF":5.4,"publicationDate":"2026-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146074378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research work focused on the green synthesis of gold nanoparticles (AuNPs) using a novel photobiological engineering method with an aqueous extract of fresh Gardenia jasminoides (G. jasminoides) leaves (AuNPs/ExGj); which was used as a reducing-stabilizing (RS) agent, for the first time. A reactor with narrow-band LEDs of different colors (blue, green, yellow, red, and white) and solar light was used to carry out the green synthesis. The synthesized AuNPs/ExGj were characterized through ultraviolet-visible spectrophotometry (UV–Vis), attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), and field emission transmission electron microscopy (FETEM-EDX). The AuNPs/ExGj were obtained in various morphologies, including spherical, triangular, pentagonal, and icosahedron (regular and irregular shapes), as well as nanorods, with average sizes between 27 and 52 nm. Moreover, the AuNPs/ExGj resulted efficient catalysts in the photodegradation of over-the-counter commercial dye derived from benzidine. The photocatalytic efficiency, using sunlight or white LED (WhL) as a radiation source, was 94.9% and 99.8%, respectively, in a reaction time of two hours.

Thorium exhibits notable environmental and health risks as a result of its prolonged half-life and radioactive toxicity, which renders the remediation of thorium-laden wastewater highly significant. A novel economical, efficient and environmentally friendly Th (IV) adsorbent was synthesized by one-step method using 3-aminopropyltriethoxysilane(APTES) as modifier to functionalize attapulgite(ATP). Characterization analysis results demonstrated that the prepared material possessed a distinct rod-shaped morphology, abundant amino and hydroxyl groups on the surface, and had good adsorption for Th(IV) in wastewater. At room temperature, the adsorption capacity of APTES/ATP for Th(IV) reached 1521.98 mg/g. The results of adsorption kinetics, adsorption isotherms and thermodynamics showed that the reaction of APTES/ATP with Th(IV) conformed to the pseudo-second-order kinetics and Langmuir isothermal adsorption model. The adsorption process of Th(IV) by this material was a monolayer endothermic reaction. The adsorption mechanism mainly involves the complexation and coordination of Th(IV) with amino, OH-and Si-OH groups in APTES/ATP, which can effectively remove Th(IV) in wastewater.

The synthesis of titania crystals from the conventional titanium precursors (alkoxides, halides) is a challenging task as the rapid hydrolysis leads to aggregates in the solution phase. In this context, Ti3C2 MXene emerged as a versatile precursor owing to their inherent sheet-like structure and easy crystallization of TiO2 from its surface under the moderate reaction conditions. The titania formation was evidenced for 16 h of hydrothermal reaction time, while the longer reaction time (30 h) showed the presence of TiO2 with co-exposed (001) and (101) facets under the assistance of NaBF4. It was revealed that the Ti3C2/TiO2 obtained at low reaction time (16 h) had an extremely negative surface charge density, which favoured the pollutant adsorption and degradation process. The electron paramagnetic spectroscopic studies indicated the presence of oxygen vacancies and Ti3+ sites, which facilitated the spatial separation of electron-hole pairs. The formation of Schottky contact between the Ti3C2 and TiO2 was confirmed by computational analysis, which additionally contributed to the overall efficiency. The findings of the present work might open an avenue for the synthesis of co-exposed faceted crystals using MXenes substrate under the wet-chemical approaches.
