A high‐performance NH 2 ‐MIL‐88B(Fe)‐SA−V for the direct catalytic oxidation of benzene hydroxylation using hydrogen peroxide as the oxidant was designed and prepared. The synthesized material was characterized by scanning electron microscopy, x‐ray powder diffraction, flourier transform infrared spectroscopy and nitrogen adsorption‐desorption. The influence of different parameters on the catalytic performance of NH 2 ‐MIL‐88B(Fe)‐SA−V for benzene hydroxylation was researched. Under optimized condition, the high yield of 22.2% and selectivity of 98.6% were obtained, while the pure NH 2 ‐MIL‐88B(Fe) only gained the yield of 1.2%. Furthermore, the V/Fe 3 O 4 catalyst was obtained by calcination of NH 2 ‐MIL‐88B(Fe)‐SA−V in N 2 for photocatalytic recycle, and the yield and selectivity of phenol were 20.2% and 98.2% respectively. And the V/Fe 3 O 4 has good photocatalytic efficiency after several recycling tests in the acid reaction condition.
