摘要：

In this study, Z-scheme NiO/BiO2-x heterojunction was successfully constructed by hydrothermal method, which can maintain strong redox potential and excellent visible light response and effectively improve the separation efficiency of photogenerated carrier. Under visible irradiation, the impact of different contents of NiO in NiO/BiO2-x on photocatalytic activity was explored, and the results shown that 3-NiO/BiO2-x had the highest photocatalytic activity. The degradation rate of 3-NiO/BiO2-x for methyl orange (MO) was 7.69 times and 19.7 times higher than pure BiO2-x and NiO, respectively. Moreover, the degradation rate of 3-NiO/BiO2-x for ciprofloxacin (CIP) was 7.54 times and 60.8 times higher than that of the pure BiO2-x and NiO, respectively. NiO/BiO2-x heterojunction can be used in the field of wastewater treatment due to their excellent degradation activity for organic pollutants.
