Fabrication And Performance Of Inorganic Metal Oxides Micro-and Nanostructures By Hydrothermal Method

Inorganic metal oxide micro-nanomaterials have been the key issues in modern materials science. In this paper,mico-nanostructures flower shape CuO was fabricated by low temperature hydrothermal process, Preparation of Co3O4 micro-sheets with porous and ZnO microspheres with porous nanosheets by hydrothermal-thermal decomposition method,and the possible formation mechanisms for these have also been discussed. The main results can be summarized as follows:1,Fabrication micro-nano flower shape CuO by low temperature hydrothermal method, and character the products. Summarized the influences of the experimental conditions, a possible growth process of the products has been studies. We also research the photocatalytic of the flower shape CuO, We find this kind of structure exhibited a high photocatalytic activity for decolorization of Rhodamine B(Rh-B) under visible light .2,Fabrication Co₃O₄ micro-sheets with porous by hydrothermal-thermal decomposition method,and character the products, Research the influence of the reactive conditions for precursor and discuss the possible formation mechanisms of the products.3,Fabrication ZnO Microspheres with porous nanosheets, and character the products. Research the possible formation mechanisms of the products, meanwhile we also research the photoresponse of this kind of micosheres under UV and visible light and the photocatalytic under visible light. We find ZnO Microspheres with porous nanosheets has an excellent photoreponse under UV and visible light and a high photocatalytic activity for MO under visible light.
