BiOCl-based photocatalysts were prepared by a solvothermal approach using different solvents as medium. BiOCl prepared by glacial acetic acid exhibits the highest separation rate of photo-induced charge pairs. Scanning electron microscope images indicate that the solvents play an essential role in affecting the crystal growth and morphology of BiOCl. Photocatalytic properties of BiOCl prepared by different solvents were evaluated using Rhodamine B, phenol and perfluorooctanoic acid as model pollutant. The results illustrate that prepared BiOCl represents different photocatalytic activities toward removal of three simulated pollutants. Among them, BiOCl prepared using glacial acetic acid as solvent displays the highest photocatalytic performance.

基于BiOCl的光催化剂是通过溶剂热法使用不同的溶剂作为介质制备的。由冰醋酸制备的BiOCl具有最高的光诱导电荷对分离率。扫描电子显微镜图像表明，溶剂在影响BiOCl的晶体生长和形态方面起着至关重要的作用。以罗丹明B，苯酚和全氟辛酸为模型污染物，评估了不同溶剂制备的BiOCl的光催化性能。结果表明，制备的BiOCl代表着去除三种模拟污染物的不同光催化活性。其中，以冰醋酸为溶剂制备的BiOCl具有最高的光催化性能。
