Application and Mechanism Study of Carbon-Based Metal-Free Catalysts in Organic Synthesis
Carbon nanotubes(CNTs),graphite oxide(GO),graphene(G),activated carbon(AC),and materials generated by AC after doping or modification are examples of carbon-based metal-free catalysts.These catalysts are used in critical chemi-cal processes like energy conversion.Due to its advantages of abundant materials,low cost,environmental friendliness,straightforward post-processing and sustainable development,carbon-based metal-free catalysts have been successfully used in the field of organic synthesis in recent years.The application of carbon-based metal-free catalysts in oxidation,reduction,sub-stitution and coupling reactions has been successfully reported.However,the research on the active site of carbon-based met-al-free catalysts used in organic synthesis is still in its early stage of development.Recent research has mostly concentrated on the characterization and study of catalysts as well as first-principles predictions for their mechanisms,but generally consistent experimental conclusions have not been reached.Therefore,the application and mechanism research of carbon-based met-al-free catalysts in the field of organic synthesis are reviewed.
