Processing and Properties of Photocatalytic Self-cleaning Ceramic

LIU Ping;WANG Xin-Chen;FU Xian-Zhi(Research institute of Photocatalysis, Fuzhou University Fuzhou 350002, China)  
Self-cleaning ceramic materials were prepared by coating photocatalytic membrane onceramic matrix. The photocatalytic behavior of these materials for degradation of oleic acid andsterilization was studied by using XRD, AES, and in-situ reaction techniques. The effect of preparation and reaction conditions including heating treatment and thickness for the membrane onphotocatalytic activity of the self-cleaning ceramics was examined. The results show that the photodegradation of oleic acid and sterilization of the self-cleaning ceramics are determined by crystalstructure, particle size, and specific surface area of the supported photocatalyst membrane.
