Abstract In this paper, cellulose‐supported SnW(S,O) 4 bimetal sulfo‐oxide catalysts (labeled as SnWSO‐C or SW@C) with exceptional catalytic performance in the reduction of MB, RhB, and Cr(VI) presence NaBH under dark conditions were synthesized via an in‐situ hydrolysis method. The catalyst system diverse tree species Pinus massoniana (Pm), Populus tomentosa Carrière (Ptc), Rice hull (Rh), Phyllostachys edulis (Pe) was investigated. 100 mL solutions MB (20 ppm), RhB (50 ppm) completely reduced by SW@Cotton, SW@Pe, SW@Rh, SW@Ptc, SW@Pm within 10, 7, 13, 4, min for MB; 8, RhB; 5, 8 Cr(VI), respectively. Among them, SW@Pe exhibits highest efficiency excellent stability, maintaining a removal rate 96% after six cycles. superior attributed unique properties cellulose, characterized low crystallinity (53.25%), minimal ash content (0.15%), lowest degree polymerization (1267). These features facilitated improved dispersion SnWSO sulfo‐oxide, leading to smaller crystal size, lower electrochemical impedance (2.24 Ω), larger electrochemically active surface area (21.86 mF/cm 2 ). This study demonstrates potential wastewater treatment, which is significant advancing future research on environmental pollution management using biomass‐based materials.

V‐/O‐Doping to Endow Ag₂S‐based Bimetal Oxysulfide with Sulfur Vacancies and Heterovalent States for Rapid Reduction of Organic and Cr(VI) Pollutants in the Dark

Advanced Sustainable Systems, Год журнала: 2025, Номер unknown

Опубликована: Янв. 13, 2025

Abstract A novel AgVOS oxysulfide catalyst for rapid catalytic reduction of toxic organic substances and Cr(VI) under dark is synthesized by a facile method. With the V/O co‐doping, doped Ag 2 S has effectively regulated electron transfer performance, hydrazine‐driven V 5+ ‐to‐V 4+ to disturb charge equilibrium, formed sulfur vacancy balanced oxygen doping maintain equilibrium. The acts as active site electrophilic nucleophilic reaction, while orbital hybridization O 2p 3p stabilizes valence state 2− . suitable ratio n (V /V ) during synthesis facilitate enhance reaction. co‐doped AgVOS‐3 prepared hydrazine content exhibits super performance 4‐NP (4‐nitrophenol), MB (methyl blue), MO orange), RhB (Rhodamine B, 20 ppm, 100 mL) dyes, which are completely reduced within 8, 10, 8 min, respectively. In comparison, Cr 6+ (50 also 6 min AgVOS‐3, indicating its good activity inorganic mixture pollutants. Furthermore, stability after cyclic tests efficiency 96.5%. Therefore, shows promising application industrial wastewater treatment.
