Abstract: Previous achievements on CO2 chemical utilization are reviewed，including CO2 catalytic hydrogenation，ammonification and esterification reaction. The mechanism and catalysts of CO2 hydrogenation reaction are discussed. The synthesis conditions as well as the application of CO2 esterification reaction products are expounded. A novel synthetic method for the preparation of cyanuric acid by CO2 and NH3 is presented in this article. The significance of CO2 chemical utilization to its emission reduction is also explored，and its study trends are prospected. The industrialization of CO2 catalytic hydrogenation and esterification reaction cannot be realized in short term. Through ammonification，synthesizing cyanuric acid with CO2 has the broad prospects for development.
