Abstract
Abstract The realization of fast carrier transport can effectively enhance photocatalytic performance. A core–shell structure of ZnO and In 2 O 3 is successfully constructed by using MIL‐68 (In) and ZIF‐8 as a substrate, forming a heterojunction. This MOF‐derived core–shell heterojunction inherits the advantages of ZIF‐8, with pores facilitating carriers transfer to the surface for reactions and a large specific surface area providing more active sites. This Z‐scheme heterojunction of ZnO and In 2 O 3 can effectively separate and improve the utilization of photogenerated carriers. The well‐designed interface of the core–shell structure achieves the rapid transfer of photogenerated carriers. The photocatalytic degradation capability of ZnO@ In 2 O 3 is enhanced by the synergistic effect of Z‐scheme heterojunction and core–shell structure. This work provides insight into the investigation of constructing core–shell heterojunctions.
