摘　　要：用NaOH和Fe(NO3)3.9H2O共沉淀法制备Fe2O3的前驱体,分别在350℃,550℃,700℃烧结得到α-Fe2O3催化剂。通过对3种活性染料的降解实验,探讨了光照和光照时间的影响,比较了不同烧结温度下所得催化剂光催化活性的大小,得出350℃烧结的催化剂光催化活性最好。The precursor of Fe2O3 was prepared by chemical coprecipitation method with NaOH and Fe（ NO3 ）3 · 9H2O. The Fe2O3 was respectively calcined at 350 ℃ ,550 ℃ ,700 ℃. Then Fe2O3 was utilized as photocatalyst for photocatalytic degradation three kinds reactive dyes . The effects of illumination and the irradiation time on the efficiency of decolorization were studied. Compared the photocatalytic activity of the Fe2O3 calcined at different temperatures,the Fe2O3 calcined at 350 ℃ has the highest photocatalytic activity.
