S vacancy modulated Zn Cd1?S/CoP quantum dots for efficient H2 evolution from water splitting under visible light

The S vacancy generated in the phosphating process of Zn x Cd 1? S/CoO QDs plays key roles enhancement S/CoP for photocatalytic hydrogen evolution under visible light. Energy band structure and interfacial compatibility heterojunctions are crucial photocatalysts promoting photogenerated charge separation transfer. Here, a combined strategy engineering quantum effect via facile is reported, first time, to modulate energy interface dots (ZCS v /CoP QDs) heterojunction. experimental theoretical investigation revealed that transformed CoO CoP QDs, more importantly, considerable amount sulfur vacancies ZCS . As result, Type II heterojunction with compatible interfaces was constructed in-situ P-Zn, P-Cd S-Co bonds, which facilitated transfer thus resulted high ability towards light (17.53 mmol g ?1 h ). This work provides an effective adaptable effect.
