Abstract: A series of nano-sized CuO-ZnO composite particles were synthesized with a UF membrane reactor and were used for the oxidation of cumene reaction. It was found that CuO-ZnO prepared by the co-precipitation method had better catalyst performance than CuO/ZnO prepared by blending CuO with ZnO with the same ZnO content. The SEM results showed that ZnO was dispersed well in CuO in the case that the ZnO weight content in CuO-ZnO was 25%. The effect of ZnO content in CuO-ZnO on the catalytic performance for cumene oxide reaction was also investigated. With increasing ZnO content，catalytic performance reach a maximum value of CHP yield of 28% and selectivity of over 84.62% at ZnO weight content of 25% under the same reaction conditions：temperature，90 ℃; CuO-ZnO particle dosage 10 g/L；airflow rate 600 mL/min.
