Interfacial Engineering of Ni(OH)2/ZIF‐67 S‐Scheme Heterojunction Boosting Charge Transfer for Cooperative Hydrogen Production
Source abstract
Abstract
Abstract Reasonable construction and design of photo‐catalysts have been widely concerned in promoting hydrogen production. Herein, a novel Ni(OH)2/ZIF‐67(NZ) S‐scheme heterojunction is proposed for photocatalytic hydrogen production. Meantime, through the coordination of interface keys, the separation and transfer of photo‐generated charges are expedited. Leading to an effectively enhanced photocatalytic hydrogen evolution performance due to the synergistic effect of built‐in electric field and interface coordination. The hydrogen production rate of NZ‐ 20 within 4 h reaches 4364.89 µmol g−1 h−1, which is 17.79 times higher than that of Ni(OH)2 and 19.46 times higher than that of ZIF‐67. Meanwhile, in situ X‐ray Photoelectron Spectroscopy (XPS) studies confirm the S‐scheme heterojunction mechanism for photogenerated charge transfer. This work improves the efficiency of photocatalytic hydrogen evolution and provides a new thought for the construction of S‐scheme heterojunction.
