采用炭吸附共沉淀方法制取了EuFeO₃纳米半导体。利用差热-热重分析（TG-DTA）、X-射线衍射（XRD）、紫外-可见漫反射光谱分析（UV-Vis）等技术对粉体进行表征。将制得的EuFeO₃降解甲基橙溶液，并通过降解效果评价其光催化性能。结果表明，制得的EuFeO₃粉体平均粒径小、分散均匀、结晶度高；活性炭的加入可以抑制团聚和烧结；在催化反应进行1 h后，体系中甲基橙的降解率达到88.63%，相较于普通沉淀法制备的EuFeO₃的光催化性能得到提高。

EuFeO₃ nano semiconductor is prepared by carbon adsorption coprecipitation method,and characterized by mean of differential thermogravimetric analysis (TG-DTA),X-ray diffraction (XRD) and UV-visible diffuse reflectance spectroscopy (UV-Vis).Its photocatalytic performance is evaluated through degrading methyl orange solution.Characterization and photocatalytic experiments show that EuFeO₃ powder obtained by this method has small average particle size,uniform dispersion and high crystallinity.The addition of activated carbon can inhibit its agglomeration and sintering.The degradation rate of methyl orange in the system reaches 88.63% after 1 h of reaction,which is higher than that in the system containing EuFeO₃ prepared by common precipitation method.
