Synthesis of carbon fibers support graphitic carbon nitride immobilize ZnBr2 catalyst in the catalytic reaction between styrene oxide and CO2
Chemically fixing CO2 into the fine chemicals is a sustainable route to the utilization of CO2 and meets the requirements of green chemistry. Generally, an important intermediate, high-valued cyclic carbonates, is produced by catalyzed cycloaddition of CO2 with epoxides during the CO2 fixation. However, most of the catalysts for cycloaddition can hardly meet the standards of the green chemistry, including highly efficient, low cost, easily recoverable and recyclable etc. Therefore, in this work, an environmentally friendly composite Zn-CN/C catalyst for the cycloaddition of styrene oxide and CO2 was successfully prepared by a facile method. To this end, zinc bromide was immobilized by graphitic carbon nitride (gCN) and then supported on carbon fibers. Meanwhile, the crystal structure, types of chemical bonding, surface morphologies, and electronic transmission of the prepared catalyst were also investigated. Furthermore, the catalytic performance was evaluated by the cycloaddition reactions of styrene oxide and CO2, a satisfactory result of the moderate yield of 50-90% with a good selectivity (> 99%) was obtained. Finally, a credible mechanism of the reaction was proposed.
