摘要:
首先通过沉淀法制备BiOBr和BiOI纳米粉体,然后在主体BiOBr光催化剂中掺杂不同含量的共催化剂BiOI,充分研磨后在不同温度下进行煅烧3 h,制备了BiOI/BiOBr系列复合物,其中BiOI的质量分数分别为1 %,2 %,4 %和8 %. 采用氮气物理吸附、X射线粉末衍射(XRD)、扫描电镜(SEM)、傅里叶变换红外光谱(FT-IR)、紫外-可见(UV-Vis)漫反射(DRS)和光电流测试等技术对所制备的样品进行表征.以酸性橙II为模拟污染物, 在可见光下考察了煅烧温度和BiOI复合含量对BiOBr主体光催化剂的光催化性能的影响.研究表明,当复合BiOI的含量为4 %,煅烧温度为400 ℃时所制备的复合光催化剂表现出最高光催化性能,其降解效率分别是纯BiOBr和BiOI的1.7和1.9倍.复合BiOI促进了催化剂对可见光的吸收,同时经过研磨和煅烧形成的BiOI/BiOBr异质相结,促进了光生电子(e-)和空穴(h+)的分离,提高了光催化活性.
