In this paper,zinc oxide nanoparticles were first prepared and surface-modified.A Pickering emulsion was then prepared,consisting of nitrobenzene(oil phase),water(water phase)and the modified zinc oxide nanoparticles located on the water-oil interface.The effects of different emulsions on the removal rate of nitrobenzene by photocatalytic degradation were studied.The results proved that use of a Pickering emulsion stabilized by surface-modified ZnO nanoparticles provides an effective and novel way to intensify the photocatalytic degradation of the organic contaminant.
