Intensified photocatalytic degradation of nitrobenzene by Picketing emulsion of ZnO nanoparticles

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 th...

Description
Summary: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.
