Abstract

Different graphene size can affect the catalytic activity of the photocatalyst. In this work, a series of ZnIn₂S₄/graphene catalysts with different graphene sizes were synthesized, characterized and their photocatalytic activities were evaluated by photocatalytic hydrogen evolution. The different sizes (k) of graphene can be separated by differential centrifugation, with the decrease of graphene size, the activity of hydrogen production of the catalyst under visible light increases first and then decreases, when k = 5–7 μm, the maximum hydrogen production rate was 40.85 μmol/g·h. Furthermore, the relationship between the photocatalytic hydrogen production activity of ZnIn₂S₄/graphene and its physicochemical properties were further analyzed.
