Title Synthesis of ZnO Nanoparticles Using Solvothermal Method and Studies on Its Photocatalytic Performance
Abstract
In this paper the first part is the synthesis of ZnO nanoparticles with different morphology and size using solvothermal method by changing the solvent. The samples were characterized by UV-Vis spectrum，X-ray diffractometry，TEM. The shapes include sphere，short stick，long stick and hexagonal prism.This paper also compared the photocatalytic performance of ZnO nanoparticles with different shapes .The second part is the synthesis of long-stick ZnO nanoparticles with various ratios of length to diameter using solvothermal method which used ethanol as the solvent and added different surfactants.The samples were characterized by UV-Vis spectrum ，X-ray diffractometry and TEM.And their photocatalytic performances were also investigated .
Keywords ZnO nanoparticles ,solvothermal method ,photocatalysis
