Abstract

Nano TiO2 photocatalyst is a kind of polymorphism catalyst, it have small particles that make it difficult to disperse, difficult to recovered, and has the little measure contact area. However the SiC foam ceramics material with highly porous, low alloyed steal bulk density and three-dimensional model, coalescence pore structure. To prevent the application of photocatalyst happen, this article aim at studies on the preparation and properties of nano TiO2 photocatalyst based on the SiC foam ceramics, which in order to offer help to the widespread application of photocatalyst. The study results confirms that the optimum dip times is 4 times when load the coating on the surface of SiC foam ceramic with soaking technology; Stereoscopic photograph show that the modified nano TiO2 photocatalyst white coating on the surface of SiC foam ceramic is uniform;EDSanalytic result show that the main elements of the modified nano TiO2 photocatalyst white coating on the surface of SiC foam ceramic compose of Ti, O, Al ,Si; The photocatalytic efficiency of A,Si-Codoped TiO2 coating is better than nano TiO2 powders.
