The characterization of BiOCl was performed by using XRD, SEM, and DRS, and the influence of precursor pH value on the structure of BiOCl and the degradation of 8-hydroxyquinoline was investigated. The results show that with the increase of the pH value of the precursor, the exposure of {001} crystal plane, the band gap energy, and the catalytic activity decrease. The decrease of catalytic activity can be attributed to low band-gap energy and high photo-generated carrier recombination efficiency. Further investigate the effect of the pH value of the degradation system on the reactivity of BiOCl. The results show that the change of pH value changes the adsorption behavior of 8-hydroxyquinoline on BiOCl surface and then affects the reactivity of the catalyst. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
