摘　　要：利用微乳液法制备纯的Fe2(MoO4)3催化剂,并通过TG、XRD、SEM对产物进行表征.以Fe2(MoO4)3为类芬顿催化剂,探讨不同pH条件下对结晶紫的催化降解性能.结果表明,在中性条件下,结晶紫的降解率依然能达到91.00%.并且,当pH在3.0～9.0时,pH对结晶紫降解率的影响都不大.同时详细探讨了Fe2(MoO4)3催化剂可能的催化降解机理.The pure Fe2 （MoO4 ）3 catalyst was successfully synthesized via microemulsion method. The characterization of the product was measured by TG, XRD and SEM. Degradation of crystal violet solution at different pH value conditions was studied using Fe2 （MoO4 ）3 as catalyst. The results showed that the degradation ratio of crystal violet solution reached 91.00% at neutral condition. Moreover, the catalytic activity was slightly affected by the solution pH in a wide range of 3.0-9.0. At the same time, the possible reaction mechanism was proposed in detail.
