ZnO/g-C3N4 photocatalysts were prepared by solid-state grinding method at room temperature using Zn（CH3COO）2,NaOH and g-C3N4 powders as raw materials.Sodium dodecylbenzenesulfonate powder was added as a surfactant.The photocatalytic properties of the composites were studied.Results showed that ZnO/g-C3N4 composites formed after solid-state grinding and that g-C3N4 was refined into thin sheets.The addition of sodium dodecylbenzenesulfonate powder promoted the phase transformation of g-C3N4.When the content of g-C3N4 was low,the product assumed a nanoflower morphology,which was composed of a large number of ZnO nanosheets loaded on g-C3N4 flakes.When the content of g-C3N4 was higher,the produc presented many 2D g-C3N4 nanosheets loaded by ZnO nanocrystals.The synthesized ZnO/g-C3N4 composites exhibited good visible-light photocatalytic activity to methylene blue.
Key words： ZnO; g-C3N4; photocatalysis; solid-phase grinding
