dc.description.abstractConstructing heterojunctions and designing advanced structures are effective approaches to enhancing the photoelectrochemical performance of semiconductor photocatalysts for solar energy conversion. Here, we have developed a sequential chemical etching, sulfidation, and cation-exchange strategy for preparing multi-shelled ZnS-CdS rhombic dodecahedral cages (RDCs) with tunable compositions and shell numbers from 1 to 5. Yolk-shelled Zn-based zeolitic imidazolate (ZIF-8) RDCs are first synthesized by chemical etching of ZIF-8 rhombic dodecahedrons. Sulfidation of the yolk-shelled ZIF-8 RDCs leads to the formation of multi-shelled ZnS RDCs, which are further converted into multi-shelled ZnS-CdS RDCs via a cation-exchange reaction. The composition of the multi-shelled ZnS-CdS RDCs can be tuned by varying the cation-exchange reaction time, and the shell number can be adjusted by changing the size of ZIF-8 precursors. Because of the heterojunction formed and the unique hollow structure, these triple-shelled ZnS-CdS RDCs with optimized composition show enhanced photoelectrochemical performance for solar water splitting.en_US
