Research progress on thermal catalytic conversion of carbon dioxide
Due to the high chemical inertness of CO2 molecules,selective activation and controllable conversion of CO2 become extremely challenging.Compared with electric-or photo-driven catalytic conversion,thermal-driven heterogeneous catalytic conversion of CO2 is a simple method with adjustable target products and high product yield.Most importantly,the value-added products obtained from the reduction or non-reduction of CO2 can effectively promote the utilization of CO2 and alleviate the greenhouse effect,which is of great significance in the fields of environmental protection,energy,and materials.In this review,the development status quo on the thermal-driven heterogeneous catalytic conversion of CO2 for the synthesis of CO,CH4,formic acid,methanol,hydrocarbons,and other fine chemicals were reviewed,with the emphasis on the research progresses on reaction mechanism,catalysts and reaction process.Moreover,the existing problems and the future development directions were discussed.
