Abstract

In this work, we designed and prepared the novel TiO₂@ZnIn₂S₄ nano-sized hollow structure via templating method assisted by hydrothermal synthesis process. Its unique hollow structure and type-II heterojunction between TiO₂ hollow nanospheres and ZnIn₂S₄ nanosheet can provide enough interior cavities and transfer paths for the light absorption and charge quick migration. The crystal structure, morphology and charges separation property were measured. The characterization results show that the hollow-structured TiO₂@ZnIn₂S₄ was successfully prepared, and the optimal sample exhibited excellent photocatalytic hydrogen generation compared with TiO₂/ZnIn₂S₄ cluster exceeding by a factor of 1.1 under overall light irradiation. Specially, the detailed mechanism of the photocatalytic H₂ evolution and charge carrier migration for the as-prepared TiO₂@ZnIn₂S₄ hollow nanosphere was also studied.
