Published: Jan. 1, 2025

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.
