This review summarizes the research progress of non-noble metal catalysts for carbon dioxide methanation. The methanation reaction converts CO₂ and H₂ into methane (CH₄), a valuable fuel and chemical feedstock. However, the reaction faces challenges in terms of kinetics and thermodynamics, requiring the development of efficient catalysts. Non-noble metal catalysts, such as Ni, Co, Fe, and Mo-based catalysts, have gained attention due to their high catalytic activity and lower cost compared to noble metals. The review discusses the thermodynamics and kinetics of the reaction, highlighting the effects of catalyst supports, preparation methods, and promoters on catalytic performance. It also examines the impact of reaction conditions such as temperature, pressure, space velocity, and H₂/CO₂ ratio on catalyst performance. The mechanism of CO₂ methanation is summarized to provide a comprehensive understanding of the process. The paper aims to deepen the understanding of non-noble metal catalysts in CO₂ methanation reactions and provide insights for improving catalyst performance. The review emphasizes the importance of optimizing catalyst design and reaction conditions to enhance the efficiency and selectivity of CO₂ methanation. Key findings include the role of support materials in improving catalyst activity, the influence of reaction temperature and pressure on conversion and selectivity, and the importance of promoters in enhancing catalytic performance. The study also highlights the potential of non-noble metal catalysts in reducing carbon emissions and achieving sustainable carbon utilization.This review summarizes the research progress of non-noble metal catalysts for carbon dioxide methanation.
