This study presents the synthesis of a NiCo2O4/AC by hydrothermal technique. NiCo2O4 nanorods were decorated with tamarind shell-derived activated carbon to create a composite electrode with enhanced conductivity and high surface area. The NiCo2O4 improves pseudo capacitance, while the activated carbon provides a porous structure that facilitates fast ion and electron transport. The activated carbon’s sheet-like morphology acts as an ion buffer, shortening diffusion pathways. The composite electrode was characterized and exhibited excellent electrochemical performance in asymmetric capacitors. The NiCo2O4/AC composite electrode exhibits a specific capacitance of 1833 Fg−1 at 1 Ag−1. The constructed NiCo2O4/AC//AC device demonstrates an operating voltage window of 0 –1.6, providing a substantial energy density of 40.6 Whkg−1 at a power density of 2244 W kg−1. These outcomes highlight the promise of the NiCo2O4/AC composite for practical energy storage applications.

In this report, we have isolated and structurally characterized seven novel heteroleptic complexes (C1-C7) synthesized from Mn(II), Cu(II), Ag(I), Rh(III) and Pd(II) with 2,4,6-tris-(2-pyridyl)-1,3,5-triazine (TPT) and thiourea (Tu). Elemental analysis, molar conductance, IR, TGA, ESI-MS, 1D and 2D-NMR techniques (1H-, 13C-, 1H-1H COSY and 1H-13C HSQCAD), UV.Vis., and EPR spectroscopy have been used to characterize these compounds. The crystal structure of C5 was evaluated by single-crystal X-ray diffraction, revealing the triclinic character of the rhodium complex. All of the compounds showed a broad spectrum of antibacterial and cytotoxic action. The in vitro antibacterial analysis demonstrated that the percent activity index of C2 was superior in comparison to Ciprofloxacin. The cytotoxic activity of the compounds was also evaluated against four human cancer cell lines: HeP-2, HePG2, MCF-7, and HeLa. The results revealed that C2 has the most toxicity (IC50 = 6.13 ±0.7 µM and 7.48 ± 0.6 µM) against HeLa and HeP2 cell lines, respectively. DNA binding assay of synthesized compounds were performed. The findings indicted that DNA is indeed a potential biotarget for all compounds. The ability of these metal complexes to interact with and affect DNA function supports their potential as therapeutic agents in cancer treatment. Superoxide dismutase (SOD) activity of the compounds has also been assessed by NBT assay. In addition, the modes of binding of the compounds with human serum albumin (HSA) were explored by molecular docking analysis. The molecular docking experiments revealed varying degrees of binding affinity and intermolecular interaction between the tested compounds and HSA.

In this work, we have developed, for the first time, heterostructures based on Cu3TeO6 (CTO) with a strong interaction with a well-studied g-C3N4 (GCN) semiconductor. This has been carried out to mitigate the drawbacks of CTO for its application as photocatalyst in H2 production. In this sense, the resulting heterostructure presented higher activity than the pure CTO and GCN (113, 85, and 42 µmolH2/mg, respectively). The methodology employed to synthesise the heterostructure was a hydrothermal synthesis on the surface of GCN to ensure a strong interaction between both materials by growing the CTO crystal in presence of GCN. The physicochemical characterisation of the materials by XRD TG, SEM, TEM, and FTIR revealed that the synthesis was successfully developed and that Cu3TeO6 grew on the g-C3N4 surface. Indeed, this novel synthesis of the heterostructure based on CTO has huge interest for its application in H2 production due to the redox capability of the materials, observed by UPS and UV–Vis spectroscopies. The enhancement of the catalytic activity of the heterostructure with respect to the pristine materials was associate to the strong interaction between both components, the catalytic effect of Cu species, and the improved charge transfer. Indeed, a lower e− − h+ pair recombination rate was observed by steady PL analysis with respect to the pristine GCN material. These results indicate that it is possible to synthesise heterostructures based on metal tellurates with improved catalytic activity of the mixture with respect to the pristine material in a relevant energy application such as H2 production.

The complex perovskite materials are of great interest due to the coexistence of ferri/ferromagnetic which provides unique optoelectrical and physical properties. The semiconducting nature of these materials allows them for multiple applications in catalysis and electronics. Here, the modified citrate sol–gel approach has been effectively used to synthesize the nanoscale crystalline triple perovskite Sr3Ni2WO9 (SNWO), with an average crystallite size of 250 Å. X-ray diffraction was primarily used to examine the structure of the SNWO triple perovskite, and the Rietveld analysis was then used to analyze it. With a cell volume of 330.15 Å3, the phase pure perovskite compound crystallizes in the P12/m1(10) space-group at room temperature, displaying a monoclinic structure with crystal parameters of a = 7.84 Å, b = 5.56 Å, and c = 7.57 Å. Upon photocatalytic study, the material showed efficient degradation of organic complexes with 99 % and 82 % degradation efficiency for dye mixture and antibiotic mixture which are contaminants of emerging concerns within 90 min of illumination with LED light (30 W) indicating the photocatalytic prowess of the material.

To solve the global energy and environmental problems, there has been active research on heterogeneous particulate photocatalysts for hydrogen (H2) production by water splitting. Although such photocatalysts are typically composed of a semiconductor photocatalyst and a noble metal co-catalyst, there has not been sufficient studies on the effects of the sizes of co-catalysts as small as nanoclusters consisting of a few to tens of atoms. In this study, we have fabricated a new type of particulate photocatalysts deposited with platinum (Pt) nanoclusters consisting of approximately 15 atoms or fewer as a co-catalyst and evaluated the H2 evolution activities from an aqueous solution. The Pt nanoclusters were generated by a dry fabrication method using magnetron sputtering (MSP), which simplifies the synthetic process, and they were directly embedded on photocatalyst powders, titanium(IV) oxide (TiO2) and graphitic carbon nitride (g-C3N4). The Pt nanoclusters could work as a photocatalytic co-catalyst equivalent to ordinary Pt nanoparticles by a well-known photodeposition method (wet process). Furthermore, the optimal amount of Pt co-catalysts to improve the rate of H2 production was found to be 0.1 wt% in the diluted sample from photocatalyst powders deposited with Pt co-catalysts of 1 wt%, and the improvement in activity by diluting samples was more pronounced for the Pt-nanocluster-deposited photocatalyst than for the Pt-nanoparticle-deposited photocatalyst. Our method will be extended to the design of functional materials with Pt (including alloys) co-catalysts/catalysts for the widespread use by reducing the amount and cost of precious metals.

Tunable semiconductor nanoparticles continue to be the primary inorganic catalytic materials for photochemistry. Nanostructured semiconductor materials have unveiled a novel realm of opportunities for photodetection and photocatalysis devices. Pure and rare earth Ce-doped ZnO nanoparticles were synthesized by hydrothermal method and characterized to investigate the gas sensing abilities (especially for NO2), UV sensitivity and photocatalytic investigations. The influence of Ce dopant on ZnO’s structural, morphological and optical properties was examined. 1 % Ce doped ZnO nanostructures revealed the maximum responsivity for NO2 gas over CO, H2, NH3, and acetone gases at 100 ppm concentration and 250 °C optimised temperature. The effectiveness of the sensor was recorded against relative humidity, and it illustrated the attractive response time (11.8 s) and recovery time (56.3 s) in even 41 % humidity. Results revealed that the 1 % Ce doped ZnO-based gas sensor is recommended as a reliable NO2 gas sensor for applications in environmental safety and monitoring. Sample with 3 % Ce doped ZnO revealed the efficient performance for UV photodetection with photo detective of 420 × 108 Jones, a rise time of 0.1 s, and a decay time of 8.7 s. 3 % Ce doped ZnO nanoparticles illustrated the maximum degradation efficiency of 98.4 % for DB71 under solar irradiation. The effect of catalyst weight and pH on the degradation efficiency was investigated. The five-cycle photostability test of selective catalyst revealed its potential for gas sensing and wastewater treatment applications.

Magnesium batteries are considered a promising alternative to lithium-ion batteries due to the abundance, low cost, and high theoretical energy density of magnesium. Metal oxide nanoparticles have shown significant potential in addressing some of these challenges like high charge/discharge rates, low conductivity, and poor cycle life by enhancing the electrochemical performance, stability, and efficiency of magnesium batteries. In this study, nanoparticles of magnesium oxide (MgO), manganese oxide (Mn2O3), and magnesium manganese oxide (MgMn2O4) are synthesized using the gel-combustion method. These nanoparticles are analyzed through X-ray diffraction (XRD) to determine their crystallite size. Their surface morphology is studied using Scanning Electron Microscopy (SEM), revealing agglomerated and uneven surfaces. The elemental composition is identified by using energy-dispersive X-ray spectrometry (EDX). Electrochemical properties are assessed using Cyclic Voltammetry (CV) and Galvanostatic Charge-Discharge (GCD) analysis. Compared to single metal oxides, the synthesized binary metal oxide demonstrated superior electrochemical performance. GCD results showed that MgMn2O4 nanoparticles achieved a maximum specific capacitance of 203 F/g at a current density of 2.1 A/g. Furthermore, after 1000 charge–discharge cycles, the electrode’s power density remains stable, confirming its durability. Using the prepared metal oxides as cathode, three batteries are fabricated and their properties are compared. The electrochemical cell is fabricated using MgMn2O4 as a cathode material performs better than the others and the discharge characteristics are also investigated.

Heavy metal contamination in wastewater is a severe threat to both human health and the environment. In response to this challenge, a novel nano-magnetic heteropoly acid-based organic–inorganic hybrid adsorbent, CF@[Cu2(nic)(bpy)2]2[PTA], was developed for the efficient removal of multiple heavy metal ions. This synergistic adsorbent consists of copper-containing Keggin-type polyoxometalate-based hybrid immobilized on the surface of cobalt ferrite. It features highly electronegative surfaces enriched with oxo-functional groups and magnetic properties, as well as a large surface area. Characterization of the synergistic material was performed using various techniques, including FT-IR, FESEM-EDX, TEM, XRD, VSM, and TGA. The experimental results revealed that the optimal conditions for maximum metal ion removal were achieved at pH 6.5, with a 40 mg dosage of adsorbent, an initial ions concentration of 5.0 mg L−1, and an equilibrium time of 30 min. The CF@[Cu2(nic)(bpy)2]2[PTA] nanoadsorbent exhibited maximum adsorption capacities ranging from 20.5 to 158.7 mg g−1 for the target ions. Kinetic and isotherm modeling showed that metal ions uptake followed a Langmuir isotherm model and a pseudo-second-order kinetic model, with negative ΔG° values indicating a spontaneous adsorption process. Overall, the CF@[Cu2(nic)(bpy)2]2[PTA] nanoadsorbent demonstrates great potential for heavy metal ions removal from wastewater, making it a promising material for cleaner wastewater treatment strategies.

This study presents modifications of the structural and magnetic properties of Cu0.5Cd0.25Co0.25LaxFe2-xO4 where x = 0.0, 0.02, 0.04, 0.06, 0.08, 0.1 nano-structured spinel ferrites through doping La3+ ions. The analyzed ferrites powder were produced via the sol–gel combustion process and characterized using X-ray Diffraction (XRD), High Resolution Transmission Electron Microscopy (HRTEM), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Analysis (EDAX), Fourier Transform Infrared Spectroscopy (FTIR), and Vibration Sample Magnetometer (VSM). The creation of a single-phase nanostructure in the produced material was verified by XRD analysis. The influence of La3+ ions on crystallite size, grain size, lattice constant, dislocation densities, bulk densities, porosity, and hoping lengths was assessed. XRD analysis confirms that all samples exhibit the formation of the cubic spinel structure with Fd3m space group. The crystallite size (23 nm-8 nm) and lattice dimension (8.4610 Å-8.3690 Å) showed a significant random nature corresponding to the doping Fe3+ (0.67 Å) by small La3+ (1.06 Å). The IR absorption spectra recorded in the 350–2500 cm−1 range, with the tetrahedral complexes showing higher frequency band (ʋ1) at 536–666 cm−1 and the octahedral complexes generating the lower frequency band (ʋ2) at 390–428 cm−1, and they are the characteristic feature of spinel structure. The images obtained through FESEM and HRTEM reveal the existence of particles characterized by spherically cubic shaped crystallites. The measurement of the magnetic parameters was conducted through VSM. The observed M−H loop, with saturation magnetization (26.82 emu/g-41.61 emu/g), remanent magnetization (4.92 emu/g-14.00 emu/g), coercivity (190.68 Oe-857.24 Oe), and Magnetic Moment (1.2339–1.8895) show the soft magnetic pseudo-single domain structure. The initial incorporation of La3+ leads to an increase in Ms, Mr, Hc, and ƞΒ followed by a subsequent decrease.
