β相纳米氧化铁催化材料制备实验研究

Experimental Study on Preparation of Pure β Phase Fe2O3

作为Fenton反应的重要催化载体,氧化铁一直是环境催化领域关注的热点。氧化铁有多个晶型,其中β相氧化铁在催化领域具有良好的应用前景。但作为亚稳态物质其制备易受实验条件影响,限制了其研究及应用。针对β-Fe2O3制备过程中灼烧温度、升温速率、灼烧时间、空气湿度等影响因素进行了实验研究,确定了其最佳制备条件,能够为后续相关研究提供参考。

As the main catalytic carrier in Fenton process,Fe2O3 is widely studied in the field of environmental remediation.Fe2O3 has multiple crystal forms;β-Fe2O3 among them has a promising prospect in the field of catalysis.However,as a metastable material,the preparation ofβ-Fe2O3 is easy affected by many experimental conditions,which restricts its research and application.In this paper,the effect of calcination temperature,calcination time,air moisture on the preparation ofβ-Fe2O3 was investigated,and the optimum preparation conditions were determined,which could provide some reference for further related researches.
