摘要
Bi2O3· 3MoO3 oxide catalyst has been prepared by the sol gel pr℃ ess at lower temperature. The influences of preparation conditions and thermal treatment conditions on the morphology and structure of the catalyst have been studied by using TEM, DTA TG, FT IR, XRD and BET surface area measurement methods. It is shown that the BET surface area of Bi2O3· 3MoO3 prepared by sol gel method is larger than that of Bi2O3· 3MoO3 prepared by coprecipitation method. For the preparation of the well distribuated Bi2O3· 3MoO3 catalyst has a BET surface area of 13.2m2· g－ 1, the optimum conditions for the catalyst are :
