HPA/TiO2-ZrO2的制备及对水溶性燃料光催化降解的研究

Firstly, I use impregnation method to prepare for the carrier of TiO2 and ZrO2 silicotungstic type heteropoly acid light catalyst H3PW12O40/TiO2-ZrO2, H4SiW12O40/TiO2-ZrO2, H7PMo12O42/TiO2-ZrO2. Secondly, respectively by photocatalytic degradation of methy orange, methylene blue and alkaline magenta. As a result, methyl orange degradation of the degradation rate is the most using silicotungstic acid. Thirdly, the solid acid is showed by Fourier infrared spectroscopy. In HPA/TiO2-ZrO2 photocatalysis system, heteropoly acid significantly accelerate the relay of electronic from the surface of TiO2 and ZrO2 to O2 molecular,which changes TiO2 and ZrO2 photocatalysis reaction process, so as to improve the efficiency of photocatalysis. Then by photocatalytic degradation dye wastewater to the methyl orange, I discusses the effects of light catalytic degradation, such as catalyst dosing quantity, pH value,the times of catalyst reused and so on. Finally, I measure the reaction kinetics parameters.
