Abstract In this work, the copper-based metal organic framework material HKUST-1 was successfully synthesized by solvothermal method, vigilantly investigated using various techniques including XRD, SEM, FTIR, XPS, TG and BET. The prepared HKUST-1 was applied as a heterogeneous catalyst in oxidation of benzene to p-benzoquinone, and the influence of various reaction conditions such as role of solvents, reaction time and temperature, benzene to hydrogen peroxide molar ratio were specifically investigated. The acquired date manifested that HKUST-1 had shown superiority catalytic performance. Experimental results show that under optimized conditions, 11.96% yield of p-benzoquinone is obtained with the selectivity as high as 64.61%. In addition, the catalyst recovery and reuse test show that HKUST-1 is able to endure the harsh conditions of benzene oxidation for four runs. After the catalyst was recycled 4 times, the yield of p-benzoquinone remained above 10.87%.
