Metal-Organic Frameworks Decorated Cu2O Heterogeneous Catalysts for Selective Oxidation of Styrene

The selective oxidation of styrene with highly efficient, environmentally benign, and cost-effective catalysts are great importance for sustainable chemical processes. Here, we develop an in situ self-assembly strategy to decorate Cu-based metal-organic framework (MOF) Cu-BDC-NH2 nanocrystals on Cu2O octahedra construct a series Cu2O@Cu-BDC-NH2 styrene. Using H2O2 as green oxidants, the optimized sample Cu2O@Cu-BDC-NH2-8h could achieve 85% conversion 76% selectivity benzaldehyde under mild condition 40 °C. high performance as-prepared heterogeneous was attributed well-designed Cu+/Cu2+ interface between well porous MOF shells composed uniformly dispersed nanocrystals. alkaline properties –NH2 modification MOFs enable reaction be carried out base-free condition, which simplifies separation process makes catalytic system more friendly. Besides (od-Cu2O), cuboctahedrons (cod-Cu2O) were synthesized by adjusting added polyvinyl pyrrolidone, obtained cod-Cu2O@Cu-BDC-NH2 composite also showed good performance. This work provides useful developing efficient benign
