Z-scheme Bi2O3/Bi/ZnIn2S4 photocatalyst for enhancing the removal performance of Cr(VI), 2,4-dinitrophenol and tetracycline

Construction of heterojunctions is conventionally regarded as the prevailing technique to enhance solar-driven photocatalytic water splitting and photodegradation pollutants. Herein, we report a novel design ternary Bi2O3/Bi/ZnIn2S4 system, which was facilely synthesized satisfy these stringent criteria for sunlight removal organic ionic pollutants hydrogen evolution. could degrade 2,4-dinitrophenol (94.6%), tetracycline (96.5%), Cr6+ (96.3%) effectively under visible light give production rate 482.5 μmol·g−1·h−1 light. Based on first-principles calculations electrochemical results, our system be identified Z-scheme. Photocorrosion sulfide prohibited while catalytic capabilities are simultaneously benefited due lowered bandgap in harvesting, internal electric fields charge separations, surface plasmonic resonance enhanced electron boost.
