Two-Dimensional S-Scheme Engineering in Bi₂WO₆/S_V-ZnIn₂S₄ for Solar-Driven H₂O₂ Generation in Pure Water

The development of eco-friendly hydrogen peroxide (H2O2) synthesis through the photocatalytic oxygen reduction reaction holds significant potential for sustainable chemical engineering; however, it remains hindered by necessity sacrificial agents. Herein, we construct a two-dimensional (2D) S-scheme heterojunction interfacial coupling S-vacancy-rich ZnIn2S4 (SV-ZIS) with Bi2WO6 (BWO) nanosheets via an in situ growth method. Band alignment engineering establishes giant built-in electric field at Bi2WO6/SV-ZIS interface, which drives directional charge transfer, leaving photogenerated electrons and holes highest redox potentials accumulated on BWO SV-ZIS, respectively, O2 H2O oxidation. This spatial separation mechanism enhances both electron-hole pair dissociation efficiency (validated transient photocurrent analysis) preserves strong (reflected free-radical capturing experiments). 2D/2D architecture further amplifies migration atomic-level contact, leading to efficient H2O2 production rate 822 μmol L-1 h-1 pure water. work provides strategy designing high-performance photocatalysts toward under environmentally benign conditions.

Solar energy-utilizing photocatalysts for water purification remain essential environmental sustainability. This report presents new concepts in bismuth oxychloride/oxide/carbon nanotubes. (BiOCl/Bi2O3/CNT) composites, synthesized through a chemical deposition method involving BiOCl carbon nanotube bath, followed by surface reduction/oxidation steps. The impact of ratio and calcination temperature were explored. Characterization involved ultraviolet–visible diffuse reflectance spectroscopy (UV–vis DRS), X-ray photoelectron (XPS), fourier transform infrared (FTIR), diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX), elemental mapping, N2 adsorption/desorption analysis, electrochemical impedance (EIS). XRD analysis revealed in-situ formation α β-Bi2O3 phases, rendering the composite more responsive to visible light at 200 °C. Carbon nanotubes reduced band gap ternary yielding lower energies range compared Bi2O3. XPS identified metallic Bi0 particles, enhancing mobility charge separation. synergy BiOCl/Bi2O3/CNT-200 material significantly improved diclofenac degradation under solar simulator irradiation. Total organic (TOC) demonstrated 81 % mineralization with material. Active species trapping crucial roles HO• radicals h+ holes pollutant degradation. presence normally metastable phase °C enhanced simulation efficiency, while acted as reservoirs, aided particles. present study sets out an efficient synthesis approach photomineralization complex pharmaceutical compounds.
