Photogenerated Defect‐Transit Dual S‐Scheme Charge Separation for Highly Efficient Hydrogen Production

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(42)

Published: June 16, 2023

Abstract The rational design of a step‐scheme (S‐scheme) heterojunctions in hybrid semiconductors by avoiding unwanted charge transport paths is considered as an attractive way to achieve high photocatalytic activity hydrogen evolution reaction (HER). Here, dual S‐scheme heterojunction formed the lychee‐shaped W 18 O 49 /CdWO 4 /CdS nanostructures proposed for improving performance HER under visible light irradiation. remarkable attributed unique structure and effective separation photoinduced defect‐transit mechanism strong internal electric field. measurements X‐ray photoelectron spectroscopy (XPS), femtosecond transient absorption (fs‐TA) spectroscopy, electron paramagnetic resonance (EPR) further confirm carrier transfer pathways following mechanism. This research can provide new strategy designing improve through defect band engineering.
