碩士 / 大同大學 / 材料工程學系(所) / 99 / Poly-urethane sponge was used as templates to fabricate porous SiC,Al2O3 and phenolic-resin derived carbon. These pourous ceramic were then coated with sol-gel TiO2 and TiO2 powder(P25) to form TiO2/SiC,TiO2/Al2O3 and TiO2/C supported photo-catalysts. P25 powder was also doped with N in attempt to increase the adsorption of visible light. Surface morphology was observed in SEM, Crytal structure was identified with XRD, photo-catalysts performance was evaluated by the degradation of methylene blue solution. The result showed that:P25-TiO2/SiC has the best methylene blue degradation performance. Among the supported TiO2 catalysts. In addition, P25 is the better powder-form photocatalyst than the sol-gel derived. After N-doping , P25 can be increased in the adsorption of visible light.
