Abstract: ZnO nanoparticles were synthesized by homogeneous precipitation method in lamellar lyotropic liquid crystal (LLC) which composed of Sodium dodecyl sulfate(SDS),1-amyl alcohol(C5H11OH) and water.The photocatalytic activity of ZnO nanoparticles under UV-Vis irradiation was evaluated by using the nanoparticles as photocatalyst to degrade methylene blue (MB) dye molecules in aqueous solution.Results indicated that the texture of LLC was the most regular and uniform distribution with SDS∶C5H11OH was 5∶5 when water accounts for 50%.The influence of reaction condition were also investigated and the best photocatalytic performance was obtained by using 4g/L ZnO nanoparticles and 6g/L H2O2.Finally,the ZnO photocatalyst was employ for the methylene blue in which the almost 89% dye molecules removal was achieved after 150min of UV irradiation time.
