采用固相反应法在873 K合成了Pr2InNdO7光催化剂,通过X射线衍射(XID)、比表面积(BET)、光致发光(PL)和紫外-可见漫反射(UV-Vis DRS)测试手段对其进行了表征.以亚甲基蓝(MB)为光催化反应的模型化合物,在紫外和可见光的照射下对Pr2InNdO7光催化剂的活性进行了评价.结果表明:Pr、In、Nd的质量比对Pr2 InNdO7样品的光催化活性有重要的影响,当Pr、In、Nd的质量比为1:4:1时,Pr2 InNdO7样品的紫外和可见光催化活性分别达到最大值,并且它的光催化活性明显高于纯In2O3.这显著提高的光催化活性主要归功于适量的Pr2 O3、Nd2O5与In2 O3复合增加了它的比表面积,改善了光生电子-空穴对的分离效率以及提高了其在200～800 nm区域的光吸收强度.
