Carbon Doping and Oxygen Vacancy-Tungsten Trioxide/Cu₃SnS₄ S-Scheme Heterojunctions for Boosting Visible-Light-Driven Photocatalytic Performance

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Developing ideal photocatalysts for energy regeneration and environmental remediation by combining the advantages of individual semiconductors remains a significant challenge. Herein, tungsten trioxide (WO3)/Cu3SnS4 S-scheme heterojunction composite are developed. Initially, doped oxygen vacancy (OV) was prepared on two-dimensional WO3 nanosheets direct calcination method. Subsequently, Cu3SnS4 nanoflowers produced via one-step hydrothermal process, which then used to wrap nanosheets. The close contact between Cu3SnS4, coupled with unsaturated C–OV coordination, enhanced interfacial electron transport. Under visible light irradiation, WO3/Cu3SnS4 shows an impressive H2 production rate 3345.26 μmol h–1 g–1, improvement over performances Cu3SnS4. Moreover, demonstrated highest photocatalytic tetracycline degradation efficiency, achieving 99.4% within 90 min illumination. An efficient system well-aligned band structure successfully constructed. This design effectively extends their lifetime, allowing achieve maximum efficiency in reaction.

The swift recombination of photo-induced electrons and holes is a major obstacle to the catalytic efficiency TiO2 nanomaterials, but incorporation graphene oxide out-field modification considered potent method augment photocatalytic properties. In this work, series GO/TiO2 photocatalysts were successfully optimized by microwave field. As determined transient photocurrent response electrochemical impedance spectroscopy (EIS) tests, irradiation at 600 W for 5 min on photocatalyst promoted interfacial charge transfer suppressed recombination. Through systematic characterizations, GT(600/5) exhibited highest photooxidation rate (81.5%, 60 min) Rhodamine B under visible light compared other homologous samples, owing minimum grain size (16.914 nm), enlarged specific surface area (151 m2/g), maximum wavelength (510 narrowest bandgap width (2.90 eV), stronger oxidized hydroxyl radicals (•OH). Given environmental friendliness, greenness, sustainability, study could present an efficient economical strategy synthesizing fine-tuning photocatalysts.
