Abstract

A series of Z scheme systems are constructed in three ways and the photocatalytic H₂ evolution activities are evaluated under visible light irradiation. The Z scheme system can be constructed by loading ZnIn₂S₄ onto BiVO₄. The H₂ evolution is successfully realized under the visible light without providing a sacrificial agent, and the activity is greatly improved when the graphene is acted as a solid electron mediator. The best Z scheme system of 1.0La-ZnIn₂S₄/1.5RGO/1.0RuO₂/BiVO₄ (1:5) is obtained. Its photocatalytic H₂ evolution activity and the A.Q.Y. reach 4.1 μmol g⁻¹ h and 0.8%, respectively. Furthermore, its property is characterized by various analysis techniques, such as XRD, Raman, SEM, BET and PL, and the catalytic mechanism is also discussed.
