【 摘 要 】

Material is the material basis for human survival and development, and it has a very important role in the national economic and social development. With the development of electronics and new materials industry, nano ZrO2 and its composite materials have been widely used. Twenty-first Century is the century of the development of new materials, so the development of new catalytic material is undoubtedly significant. This paper mainly introduced classification and the presentation of the catalytic material and zirconia properties and applications, by sol-gel method. The prepared a series of Fe2O3-Al2O3-CeO2-ZrO2 catalytic materials, respectively by IR, UV, scanning electron microscope(SEM), X-ray diffraction (XRD) and photocatalytic modern measurement analysis method on product was characterized. Based on the analysis of the influence of the composition on the properties of the material, the optimal composition is selected. The results show that, the thermal stability of the pure ZrO2 is relatively low, with the addition of metal elements can effectively improve the ZrO2; scanning electron microscope image analysis shows that adding metal element effectively avoid the agglomeration of the particles; photocatalytic experiments indicated that, the doping metal elements can improve the performance of the material of photocatalytic degradation of methyl orange and Rhodamine B.
