| Abstract: | Mixed phase nano-TiO2 and mixed phase nano-TiO2/EP were prepared by Sol-gel method and the content of rutile in the mixed phase was controllable by doping hexylene glycol(HG).The catalysts are characterized by XRD,UV-visible DRS and electrochemistry method.The results show that the ratio of R/A phase in mixed crystal is fixed by regulator HG.It is different in degradation effect of dye when the ratio of mixed crystal in supported nano-TiO2 is changed.This article also investgates the photocatalytic mechanis... |
