Fe2O3掺杂非纳米TiO2的制备及其光催化性能
Preparation and Photocatalytic Performance of Non-nano TiO2 Doped with Fe2O3
摘要
Abstract
In order to improve the catalytic performance of photocatalyst titanium dioxide,titanium dioxide/iron oxide com-posite photocatalyst was prepared by solid phase method.The photocatalyst was characterized by SEM,XRD and UV spec-trophotometer tests.Methylene blue was used as the target reactant to explore the photocatalytic performance of the pre-pared photocatalyst and the optimum preparation conditions of the temperature,doping ion concentration and heating rate.The prepared photocatalyst had the best effect when the holding temperature was 500℃,the doping ion concentration was 1%,and the heating rate was 8℃/min,reaching 93.1%.Compared with 82.7%of untreated titanium dioxide,it had been im-proved.Compared with titanium dioxide in the dispersion state in the liquid system,the prepared catalyst showed that it precipitated at the bottom of the liquid in about 45～60 minutes,providing the possibility for collection and utilization.关键词
