串联催化剂上CO2催化转化制备高附加值烃类研究进展

Catalytic conversion of CO2 into high value-added hydrocarbons over tandem catalyst

  • 摘要: 将CO2作为可利用的碳资源催化转化为高附加值化学品或液体燃料对于节能减排和碳资源的循环利用具有重要意义。由于CO2分子的化学惰性及高的C–C键耦合能垒,导致CO2的选择性活化及可控转化极具挑战。近年来,随着研究的不断深入及串联催化体系的构建,世界各国研究者在CO2催化加氢制备高附加值烃类方面取得了突破性的研究进展。然而,在串联催化过程中,Fe基催化剂或金属氧化物与分子筛间的协同匹配、活性组分间的组装方式、分子筛的孔道结构及酸性、以及反应条件及气氛均对CO2加氢的产物分布影响显著。有鉴于此,本综述针对CO2加氢制备高附加值烃(低碳烯烃、异构烷烃、汽油及芳烃)的串联催化反应体系,重点介绍串联催化剂上影响CO2活化、转化及目标产物生成的关键因素以及串联催化剂的稳定性,并在此基础上对CO2催化加氢的未来和前景进行总结和展望。

     

    Abstract: The conversion of CO2, an abundant carbon resource, into high value-added chemicals or liquid fuels is an attractive way to mitigate carbon emissions, which is also a sustainable approach for the cyclic utilization of carbon resources. However, the selective activation and controllable conversion of CO2 is challenging because of the inertness of CO2 and high C–C coupling barrier. In recent years, some obvious breakthroughs on CO2 hydrogenation to high value-added chemicals or liquid fuels have been made by construction of a tandem catalytic system. For the tandem catalysis, the matching of Fe-based catalyst or metal oxides and zeolites, the assembly between the two active sites, the pore structure and acidity of the zeolites, as well as the reaction conditions and atmosphere all have important effects on the product distribution. Herein, the critical factors affecting the CO2 activation and conversion and the formation of the target products, as well as the stability over the tandem catalysts are summarized. Finally, an outlook is provided.
