Year: 2025
Type: article
Abstract: The construction of efficient Z‐scheme heterojunctions is considered as a promising approach to improve the transfer and separation of photogenerated carries in the field of photocatalytic hydrogen evolution from water splitting. Herein, a novel CdS/UiO‐66(Ce) with Z‐scheme heterostructure is successfully fabricated from metal sulfide CdS and cerium‐based UiO‐66 metal–organic framework via a hydrothermal method. The Z‐scheme CdS/UiO‐66(Ce) heterojunctions can provide abundant active centers, broaden the response range to visible‐light region, accelerate the transfer of interfacial charges, and suppress the recombination rate of photogenerated electron–hole pairs. As a result, CdS/UiO‐66(Ce) (ω(CdS) = 30%) exhibits a hydrogen production rate of 1.975 mmol g −1 h −1 , which is 19.1 times higher than that of UiO‐66(Ce). Overall, this article may provide a new pathway for the rational design of efficient Z‐scheme heterojunctions with photocatalytic hydrogen evolution.
