Research progress on thermal catalytic conversion of carbon dioxide

CO_(2)分子较高的化学惰性导致其选择性活化及可控转化极具挑战。相对于电和光驱动CO_(2)催化转化反应,热驱动CO_(2)多相催化转化反应具有操作简便、目标产物可调且产品收率较高等优势。通过该类反应实现CO_(2)还原或非还原制备多种化学品,既可促进CO_(2)的资源化利用,又可有效缓解温室效应,在环保、能源和材料等领域具有重要意义。该文对热驱动多相催化CO_(2)转化为CO、CH_(4)、甲酸、甲醇、碳氢化合物和其他精细化学品的研究现状进行了综合评述,重点讨论了反应机理、所用催化剂及反应体系的研究进展,并对其未来的研究方向进行了前景展望和探讨。

Due to the high chemical inertness of CO_(2) molecules,selective activation and controllable conversion of CO_(2) become extremely challenging.Compared with electric-or photo-driven catalytic conversion,thermal-driven heterogeneous catalytic conversion of CO_(2) 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 CO_(2) can effectively promote the utilization of CO_(2) 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 CO_(2) for the synthesis of CO,CH_(4),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.
