The Preparation Of ZnO And ZnO Nanocomposite And Its Performance Study

Recently,various ZnO nano structures have been synthesized by a great many method?.However,preparing ZnO nano structures with large scale and high quality is still a great challenge.Here,we used a facile hydrothermal method to prepare nano-structured ZnO in mass production.We investigate the effect of reaction time,reaction teruperature and the molar ratio of reaction substance on the structure of the ZnO.Meanwhile,ZnO is a semiconducting photocatalyzer in itself.In order to improve the activity of ZnO we modified ZnO through loading some noble metals such as Ag,Pd and Au.Moreover,we draw a conclusion that ZnO can not only load noble metal but also observe its high selectivity by TEM,which provides a better point of departure for photocatalyzer and offers considerable potential for future application.We consider the ZnO-loaded noble metal compound as the photocatalyzer and conduct the controlled experiment of pure ZnO nanomaterial.The test results show that ZnO-loaded noble metal compounds with nano structure can enhance the sterilization effect and after its sterilization effect reflects obvioLisly loaded noble metal we can see clearly that it have an important influence on the photocatalytic activity of the material.
