摘要
以Bi(NO_3)3·5H_2O、KBr和KI为原料,以粉煤灰漂珠(FACs)为载体,通过中和水解制备了BiOBr/BiOIFACs复合光催化剂。以50W蓝光灯为光源,罗丹明B为目标物,考察了制备过程的pH值、保温处理温度和保温处理时间对可见光光催化性能的影响。结果表明,BiOBr/BiOI-FACs复合光催化剂的最佳组装条件为:pH值8.0,保温处理温度160℃,保温处理时间12h。
BiOBr/BiOI-FACs composite photocatalysts were successfully prepared by neutralizing hydrolysis method,with Bi（NO_3）_3·5H_2O,KBr and KI as raw material. The p H value,treatment temperature and treatment time of preparation process were investigated. Rhodamine B was used as the target pollutant,the photocatalytic activity of BiOBr/BiOI-FACs composite photocatalysts was tested by 50 W LED blue light irradiation. The results show that the best synthetic conditions were obtained as following： pH value,treatment temperature and treatment time were 8. 0,160 ℃ and 12 h,respectively.
