摘要：A novel ZnAl2O4/Bi2MoO6 heterostructures have been successfully prepared by co-precipitation and hydrothermal method. Excellent photocatalytic performance and stability of the composites was exhibited in the degradation of methylene blue dye solution under UV light irradiation, and seriously affected by the ZnAl2O4 content in the heterostructures. Moreover, the highest MB removal was 86.36% at 3 h under UV irradiation over 0.5 wt% ZnAl2O4/Bi2MoO6, increased by 35.20% of pure Bi2MoO6 and 72.03% of ZnAl2O4, respectively. The enhanced photocatalytic efficiency of composites was contributed to the rapidly separation of photogenerated electrons and holes. Additionally, the ZnAl2O4/Bi2MoO6 were also used to treat the biochemical wastewater of industrial eucalyptus chemimechanical pulp, which demonstrates a high COD removal of 50.88%. This study provides that Bi2MoO6 based heterogeneous photocatalysts show a promising perspective in the industrial effluents treatment. ? 2019 Elsevier B.V.
