摘要：Photoelectrochemical(PEC)hydrogen production is of great interest as an ideal avenue towards clean and renewable ***,the instability and low energy conversion efficiency of photoanodes hinder their practical *** we address these issues by introducing a hole extraction layer(HEL)which could rapidly transfer and consume photogenerated *** HEL is constructed by reduced graphene oxide(RGO)and other cocatalysts that enable rapid transfer and subsequent consumption of holes,***,we showcase a high-stability photoanode composed of CdSeTe nanowires(CST NWs)and RGO/PdS nanoparticles(PdS NPs)based *** photoanode achieves excellent photocorrosion resistance,which allows stable hydrogen evolution for>2 h at 0.5 VRHE.
