Highly conversion of CO2 into cyclic carbonates under solvent free and ambient pressure conditions by Fe complex cyanide

Methods of conversion of carbon dioxide into valuable chemicals are of great demands but their development is still challenging. Herein, we developed an efficient green and facile synthetic method for the preparation of a Fe complex cyanide. The target catalyst performs high catalytic activity for the cyclic reaction of carbon dioxide and epoxide under solvent free and ambient pressure. Meanwhile, the effect of morphology of different catalyst were also investigated by the kinetic and thermodynamic study. In addition, the catalyst can be recycled and reused at least five successive cycles without significant decrease in the catalytic activity. This target catalyst thus represents one of the efficient and recyclable systems reported for the cyclic reaction in industry
