The uncontrolled release of CO2 gas and synthetic dyes severely threatens environmental quality, demanding the need for sustainable remediation strategies. Activated carbon (AC), distinguished by its high surface area, abundant active sites, and robust structural stability, demonstrates excellent capacity for adsorbing CO2 and dye molecules. In this study, a novel silica-impregnated activated carbon (SiO2@AC) composite was synthesized from waste rice (WR) via synergistic chemical activation using Na2CO3 and KOH. The composite exhibited a high surface area of ∼400 m2/g with uniform microporous structure (average pore size of 1.71 nm), as confirmed by XPS, PXRD, FTIR, SEM, EDAX, RAMAN and BET analyses. CO2 adsorption capacity reached 72 cm3/g at 280 K and 1 bar, with negative ΔHads values ranging from 83.51 to 1.48 kJ/mol, indicating physisorption. Dye adsorption experiments revealed maximum capacities of 66.04 mg/g for crystal violet (CV) and 78.23 mg/g for methylene blue (MB), fitting well with the Langmuir isotherm model for CV and the Temkin isotherm model for MB. Kinetic analyses confirmed a predominantly physisorption-driven mechanism with weak chemical interactions for both CV and MB. Collectively, these findings demonstrate that rice-waste-derived SiO2@AC is a multifunctional, sustainable adsorbent, aligning with circular economy principles by valorizing agricultural residues for environmental remediation.

The monitoring of Cr(VI) ions presents extremely high standards in the hydrolysis/acid-base stability, detection sensitivity, anti-interference capability and accuracy of MOFs-based probes. Immobilization of rare earth ions (Ln3+) onto a stable luminescent Zr-MOF for dual fluorescence signals offered organic modules and Ln3+ sites, constitutes a feasible yet challenging strategy for efficient ratio fluorescence detection of Cr(VI). Herein, a novel Tb@Zr-MOF with dual emission signals (I391, I426 from Zr-MOF, I490, I546, I586, I622 from Tb3+) was fabricated by anchoring Tb3+ ions into a Zr-MOF inherently possesses bright blue fluorescence, utilizing the principles of antenna effect and photo-induced electron transfer (PET). Subsequently, it was deployed for effectively identification and quantitative detection of Cr2O72− and CrO42− analytes, utilizing the stable intensity ratio relationship of fluorescence signals (I391–I546) originated from Zr-MOF (I391) and Tb3+ (I546). Notably, the detection accuracy for Cr(VI) ions has been significantly improved due to the inherent cooperative quenching response mechanism associated with its dual fluorescence emission centers. It was determined that Tb@Zr-MOF exhibited a highly sensitive response towards both Cr2O72− and CrO42−, achieving fairly low detection limits (DL) of 6.77 ppb and 4.74 ppb, and the corresponding notably high quenching constants (Ksv) of 3.95 × 105 M−1 and 7.91 × 104 M−1, respectively. More ingeniously, even within an aqueous environment containing complex cations and anions or acidic and basic components (pH = 2–13), it still exhibited a reliable fluorescence quenching response towards the target analytes. This study offers a highly viable reference for the design of innovative and efficient ratio fluorescence responsive typed MOFs-based photochemical sensors.

Hexagonal layered Na2T2TeO6 (T = Co1/3Ni1/3Cu1/3) and Na2Z2TeO6 (Z = Co1/4Ni1/4Cu1/4Zn1/4) have been prepared by solid-state reactions. According to the X-ray Rietveld refinement, Na2Z2TeO6 is isostructural with its honeycomb-ordered constituents Na2M2TeO6 (M = Co, Zn), space group P6322. For Na2T2TeO6, however, only subcell (ignoring T/Te ordering) could be successfully refined despite presence of weak superstructure reflection. This is attributed to intergrowth of two packing modes with similar lattice parameters: P63/mcm (characteristic of Na2Ni2TeO6) and P6322. According to magnetic susceptibility and heat capacity measurements, both materials undergo antiferromagnetic ordering at low temperatures with negative Weiss temperatures of −38 and −26 K for the T- and Z-compositions, respectively. The Néel point of Na2T2TeO6, 16.9 K, is considerably lower than those of its Ni and Co constituents (both being about 27 K), in contrast to the sister system, monoclinic Na3T2SbO6, where TN is intermediate between those of Ni and Co constituents. Further lowering of the Néel point in Na2Z2TeO6, 8.6 K, is attributed to the diamagnetic dilution with Zn2+.

Using solar energy to produce hydrogen and oxygen through photocatalytic decomposition of water is an ideal way to deal with energy crisis and environmental pollution. In this research, a new one-dimensional covalent organic framework (1D COF) was designed and synthesized through Schiff base condensation reaction between 4,4′,4″,4‴-(porphyrin-5,10,15,20-tetrayl) tetraaniline (TP) and 4,4'-(pyrimidine-4,6-diyl) dibenzaldehyde (PA), which simultaneously incorporates pyrimidine-based hydrogen evolution units and porphyrin-based oxygen evolution units. Experimental data confirmed that the as-prepared TP-PA-COF exhibited excellent bifunctional catalytic performance of photocatalytic hydrogen and oxygen production under visible light illumination. Its performance advantages mainly come from the material's highly ordered crystal structure, large specific surface area and excellent pore characteristics. Specifically, the pyrimidine units, acting as electron acceptors and active sites for hydrogen evolution reaction (HER), promote the accumulation of electrons and accelerate the proton reduction reaction; the porphyrin units, serving as electron donors and active sites for oxygen evolution reaction (OER), efficiently enhance visible light harvesting and accelerate the migration of photoinduced electrons. This synergistic effect enables TP-PA-COF to achieve hydrogen production rate of 37.4 mmol g−1·h−1 and oxygen production rate of 7.4 mmol g−1·h−1 in photocatalytic reactions, respectively. Furthermore, the material maintains good stability after three cycle tests. This research provides new insights for constructing efficient and stable COF-based bifunctional photocatalysts and realizing visible light-driven overall water splitting.

In this study, two novel one-dimensional coordination polymers (CPs), [Zn2(bib)(3F-PAA)4]n (1) and [Cd(bib)(3F-PAA)2]n (2), were synthesized using a solvothermal method involving a mixed-ligand strategy with 1,4-bis(imidazole)butane (bib) and 3-fluorophenylacrylic acid (3F-PAA). Structural analysis via single-crystal X-ray diffraction revealed square pyramidal geometry around Zn(II) in 1 and distorted octahedral coordination geometry around Cd(II) in 2. The CPs exhibit excellent water dispersibility, high thermal stability, and strong photoluminescence, making them suitable candidates for sensing. Both CPs demonstrated high selectivity and sensitivity in the fluorescence detection of Fe3+, Cr2O72−, and folic acid (FA) in aqueous media. The detection limits achieved are remarkably low, with values of Fe3+: 0.031 μM (1), 0.026 μM (2); Cr2O72−: 0.018 μM (1), 0.019 μM (2); FA: 0.014 μM (1), 0.017 μM (2), highlighting the potential of these CPs as efficient, multifunctional fluorescent sensors for environmental and biomedical applications.

The development of non-toxic, highly biocompatible, and eco-friendly red-emitting materials, with emission spectra matching plant pigment absorption (notably phytochrome red, Pr, and phytochrome far-red, Pfr), is highly promising for plant cultivation applications. In this work, a series of Fe-doped LiAlSiO4 and LiGaSiO4 luminescent materials were successfully synthesized. Under excitation at 297 nm, LiAlSiO4:Fe3+ shows a broad red emission band ranging from 600 to 805 nm with a peak at 670 nm. Similarly, LiGaSiO4:Fe3+ exhibits a broad emission from 600 to 890 nm, peaking at 707 nm when excited at 285 nm. Both materials demonstrate good thermal stability at elevated temperatures. Notably, their emission spectra align well with the absorption spectra of Pr and Pfr, indicating strong potential for use in plant growth lighting systems. This work offers new perspectives for designing novel red-emitting luminescent materials.

The development of efficient electrocatalysts for oxygen evolution reaction (OER) is crucial for advancing sustainable energy technologies. In this work, we present a facile solid-state grinding approach to encapsulate the Anderson-type polyoxometalate [NiMo6O24H6]4- (denoted as NiMo6) into the pores of the robust metal-organic framework (MOF) MIL-101(Fe), forming a series of NiMo6@MIL composites with varying mass ratios. Among these, NiMo6@MIL-1 demonstrated superior OER performance under alkaline conditions with a low overpotential of 392 mV and a Tafel slope of 89 mV/dec at a current density of 10 mA/cm2. NiMo6@MIL-1 composite exhibited enhanced electrocatalytic activity compared to its individual components, along with excellent stability over a 4-h period. Notably, comparative studies on OER and hydrogen evolution reaction (HER) performance across composites constructed by isostructural Anderson-type anions with different heteroatoms revealed that the feature of the central atom plays a crucial role in the electrocatalytic behavior of the composite materials. The reaction mechanism of NiMo6@MIL-1 composite for electrocatalytic OER is also discussed.

This study reports a facile and cost-effective atmospheric pressure CVD method for synthesizing high-quality SnSe2 thin films. Utilizing readily available SnCl2 and Se powder precursors, this method enables the growth of highly crystalline (98.56 %) SnSe2 films with a strong (00l) preferred orientation on glass substrates. The resulting films exhibit a direct band gap of 1.51 eV, as determined by optical measurements. This simplified CVD approach presents a promising route for the large-scale production of SnSe2 thin films, with potential applications in optoelectronic devices.
