摘要
化石能源的过度利用使CO_(2)排放量逐年增大,光热催化CO_(2)甲烷化为碳资源循环利用提供了新途径。光热催化CO_(2)甲烷化结合了光催化和热催化的优势,通过降低反应活化能与温度,突破低温动力学限制,实现CO_(2)的高效催化转化。Ni基催化剂因其活性高、成本低被用于光热催化CO_(2)甲烷化。首先介绍了CO_(2)甲烷化的反应机理和反应路径,然后探讨了不同载体对光热催化CO_(2)甲烷化Ni基催化剂催化性能的调控机制,最后综述了新型负载型单原子Ni基催化剂的研究进展,可为光热催化CO_(2)甲烷化催化剂的设计与开发提供思路。
The excessive utilization of fossil energy has increased CO_(2) emissions year by year. Photothermal catalytic CO_(2) methanation is expected to provide a solution for the recycling of carbon resources. Photothermal catalytic CO_(2) methanation combines the advantages of photocatalysis and thermocatalysis, breaking through the low-temperature kinetic limitations by reducing the activation energy barrier and the reaction temperature to achieve efficient catalytic conversion of CO_(2). Ni-based catalysts are used for photothermal catalytic CO_(2) methanation due to it high activity and low cost. Firstly, the reaction mechanism and reaction path of photothermal catalytic CO_(2) methanation were introduced. Then, the regulation mechanism of different supports on the catalytic performance of Ni-based catalysts for photothermal catalytic CO_(2) methanation was studied. Finally, the research progress on the new monoatomic Ni-based catalysts was reviewed, can provide ideas for the design and development of catalysts for photothermal CO_(2) methanation reaction.
