The catalytic oxidation of styrene into value-added oxygenated derivatives is a fundamental reaction in organic chemistry that has many industrial applications. Traditionally, the catalytic processes involved in the oxidation of styrene produce a great deal of environmentally undesirable wastes. Therefore, the development of green processes for the catalytic oxidation of styrene is becoming increasingly important. To achieve the green catalytic processes is to develop new efficient catalysts. Metal-organic frameworks （MOFs） are crystalline solids, whose structures are constructed from metal ions or clusters coordinated to polytopic organic ligands. MOFs have follow advantages： （1） Large specific surface area and pore volume, （2） highly ordered pore structure and highly dispersed unsaturated metal ion sites, （3） easy design, modification and modulation, etc. These merits lead to the facts that MOFs are considered as promising heterogeneous catalysts or catalyst supports. Herein, we summarize the research process on the oxidation of styrene over various MOFs in recent years.
