Process Optimization and Application of Supported Nano-Photocatalytic Materials

Abstract:

Melt Phase-splitting[1] method was a new one of preparing supported nano-photocatalytic materials.The nano TiO₂ prepared loaded to the porous glass carrier. In this study,the technology of preparing nano TiO₂ by melt phase-splitting method was Optimization, also doing doping modifcation on them. Using nano TiO₂ photocatalyst to do photocatalytic degradation test on formaldehyde.The result had shown that: the degradation efficiency of the catalyst containing ZnO was higher than that free of ZnO. The rate of degradation of formaldehyde of the catalyst free of ZnO could reached 58.7% in 8 hours, but that of the catalyst containing was only 53.3%. Using fluorescent lamps as the light source,the photocatalytic efficiency of the catalyst free of ZnO could reached 43.2%.
