Abstract This paper reviews the effects of active metal components, support structures, and preparation methods of catalysts on their catalytic performance in dry reforming of methane (DRM), and it also explores the research directions of DRM catalysts. The DRM technology has the capacity to employ CO2 captured by oxy-fuel combustion in the cement industry to react with CH4 for syngas production, thereby facilitating the utilization of industrial CO2 resources. Catalysts are crucial for improving the conversion rates of CH4 and CO2 . Ni-based catalysts are widely used, but single Ni components are susceptible to deactivation due to carbon deposition. Bimetallic Ni-based catalysts (such as Ni-Co systems) can significantly enhance carbon deposition resistance and anti-deactivation ability while maintaining high activity. Supports directly influences the reaction efficiency and service life of catalysts. The design of micro-mesoporous composite hierarchical porous supports can balance the dispersion of active metals (micropores) and the diffusion efficiency of reactants (mesopores). In terms of preparation methods, optimizing the dispersion of active metals and metal-support interactions can improve catalyst activity and carbon deposition resistance. In the future, auxiliary technologies such as plasma and photocatalysis may be employed to activate reactants under mild conditions. Meanwhile, the coupling of DRM with renewable energy sources such as solar and wind energy should be actively explored to promote green and efficient energy conversion.
