WO3/In2S3 S型异质结中通过W-S键的界面电子转移增强光催化产H2O2
Interfacial electron transfer in WO3/In2S3 S-scheme heterojunctions via W-S bonds for enhanced photocatalytic H2O2 production
摘要
Abstract
Step-scheme(S-scheme)heterojunctions stand out owing to their unique charge transfer mechanism and the maximized redox capacities of photoexcited electrons and holes,and have been widely exploited to address the ever-growing energy crisis and environmental challenges.Herein,noble-metal-free WO3/In2S3 S-scheme heterojunctions have been developed by growing In2S3 nanosheets on porous WO3 nanofibers via interfacial W-S coordination bonds.The W-S bonds formed at the WO3/In2S3 heterointerface construct rapid charge transport channels,accelerate carrier separation,and boost photocatalytic H2O2 evolution.The optimized WO3/In2S3 composite(WI-25)delivers an outstanding photocatalytic H2O2 yield of 1349.2 μmol g-1 h-1.In situ irradiated X-ray photoelectron spectroscopy(ISI-XPS),partial density of states(PDOS)calculations,electron paramagnetic resonance(EPR),and femtosecond transient absorption spectroscopy(fs-TAS)collectively verify the S-scheme charge transfer pathway mediated by interfacial coordination bonds.This work offers a rational strategy for constructing S-scheme heterojunctions with interfacial coordination bonds to improve photocatalytic performance.关键词
