文摘

We report the synthesis of Zn_xCd_1鈥?i>xS@ZnO nanorod arrays via a facile two-step process and the implementation of these core鈥搒hell nanorods as an environmental friendly and recyclable photocatalyst for methyl orange degradation. The band gap of Zn_xCd_1鈥?i>xS@ZnO core鈥搒hell nanorods can be readily tunable by adjusting the ratio of Zn/Cd during the synthesis. These Zn_xCd_1鈥?i>xS@ZnO core鈥搒hell nanorods exhibit a high photocatalytic activity and good stability in the degradation of the methyl orange. Moreover, these films grown on FTO substrates make the collection and recycle of the photocatalyst easier. These findings may open new opportunities for the design of effective, stable, and easy-recyclable photocatalytic materials.
