Abstract：Carbon dioxide (CO2) methanation is one of the key pathways for the utilization of CO2, playing a significant role in achieving the “dual carbon” strategy and optimizing energy structures. Nickel (Ni)-based catalysts have been widely studied due to their excellent methanation activity and low cost. This review summarized the research progress of Ni-based catalysts. The thermodynamics of the methanation reaction and two typical reaction mechanisms with CO* or HCOO* were discussed. The effects of support and promoter on the catalyst structure and electronic properties are highlighted. Novel regulation strategies are introduced, including external field driving, interfacial microenvironment design, and machine learning-assisted catalyst design. This review provides theoretical references and technical perspectives for developing efficient, stable, and cost-effective Ni-based catalysts for CO2 methanation.
