Using bismuth nitrate pentahydrate and potassium chloride as raw materials, BiOCl was synthesized successfully via hydrothermal method, and its structure was characterized by XRD, SEM, and DRS. The influence of precursor pH value on the structure of BiOCl and the degradation of 8-hydroxyquinoline was investigated. The results showed that the exposure of[001] crystal plane, the band gap energy, and the catalytic activity decrease with the increase of precursor pH, which can be attributed to low band-gap energy and high photo-generated carrier recombination efficiency. The effect of degradation system pH on the reactivity of BiOCl catalyst was further investigated. The results showed that degradation system pH affected the adsorption behavior of 8-hydroxyquinoline on the surface of the catalyst, which in turn affected the reactivity of the catalyst.
