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.

Methylxanthines (MTX) are purine alkaloids commonly present in the diet. Theobromine (TBR: Theobroma cacao or T. cacao) is a second important metabolism MTX. It naturally occurs nonalcoholic beverages to stimulate central nervous system. When consumed high quantities, it has some negative impacts such as weight gain and addictions. Thus, development of well-organized electrocatalysts that can monitor trace level detection TBR food products urgently required. In this study, simple means synthesizing scheelite-type barium tungstate (BaWO4) nanoparticles integrated into carbon nanofiber (CNF) via sonochemical process discussed. BaWO4@CNF, nanocomposite modified on glassy electrode (GCE), showed better electrocatalytic activity oxidation potential range 0.9–1.6 V. Noteworthy, proposed BaWO4@CNF/GCE sensor exhibited an ultralow detecting limit (LOD: 5.2 nM) with linear 0.01–1726 μM sensitivity 2.52 μA μM–1 cm–2 by different pulse voltammetry (DPV) methods. The been applied for anti-interfering ability, repeatability, stability studies. practical applicability was tested quantitative analysis coffee dark chocolate satisfactory recoveries. Therefore, hybrid provides significant candidate electrochemical public health.

Detection of hydrazine (HZ) in food and environmental samples is immense importance. The development a highly sensitive, inexpensive, rapid electrochemical method for the detection HZ remains formidable challenge field sensors. In this study, we developed polyaniline-anchored cerium tungstate (PANI@CeW) nanostructure prepared using situ electrodeposition onto screen-printed electrode (SPE) surface (PANI@CeW/SPE) HZ. synergistic effect between PANI nanostructures showed an excellent response toward oxidation linear concentrations 10–800 50–950 nM with limit 3.5 15 amperometry DPV methods, respectively. facilitates real-time kelp, fish, drinking water samples. results obtained were cross-validated high-performance liquid chromatography analysis.
