In our previous work, the ZnIn2S4-RGO-BiVO4 Z-scheme system has been constructed successfully, which exhibits enhanced photoquantum yields and photocatalytic activity for hydrogen production. It is generally believed that morphology characteristics of catalysts is an important factor for achieving efficient photocatalytic activity. Therefore, in this work, the effect of BiVO4 morphology on photocatalytic activity of Z-scheme system was investigated. A series of BiVO4 with the morphologies of dumbbell, globose, flake, flower-like, acicular and massive shape were synthesized successfully using hydrothermal synthesis method. Then, using these BiVO4 as oxidation side photocatalyst, a series of ZnIn2S4/RGO/BiVO4 Z-scheme photocatalysts were synthesized. Their photocatalytic activities were evaluated by the hydrogen production from water under visible-light irradiation and the physicochemical properties were explored by various analytical techniques such as SEM, XRD, BET and Raman. It was found that the morphology of BiVO4 has a significant influence on the properties of ZnIn2S4/ RGO/BiVO4, such as the self-assembly of ZnIn4S4, the graphitization extents of RGO, and the special surface area of the Zscheme photocatalyst. Among the numbers Z-scheme photocatalyst, the Z-acicular shape photocatalyst has the best activity and its hydrogen production rate reaches 563.3μmol/(g⋅h). [ABSTRACT FROM AUTHOR]
