Dry reforming of methane (DRM) uses methane (CH₄) and carbon dioxide (CO₂) as raw materials to produce syngas, which has unique economic and environmental benefits. However, DRM reaction still faces the disadvantages of catalyst sintering deactivation and carbon formation. In this paper, the research progress of different DRM catalytic systems is reviewed. The conventional catalysis-alone system, plasma-catalytic system and some other catalytic systems are discussed. The key factors affecting the performance evaluation of the catalyst in the conventional catalysis-alone system were given. In particular, whether the plasma-catalytic system can achieve higher conversion than the conventional catalysis-alone system has become the focus of attention. For this reason, the reactor structure, discharge mode and the combination with catalyst were discussed. The mechanism of plasma-catalyst interaction was discussed through literature review. In addition, the possibility of other applications of DRM plasma-catalytic system is also considered. Finally, the advantages and disadvantages of conventional catalysis-alone system and plasma-catalytic system are compared. Some other catalytic systems, such as catalytic membrane reactor and solar driven methane reforming, are also introduced. Considering the research status of DRM, we can further improve the conversion and energy conversion efficiency by improving the DRM catalyst and optimizing the design of plasma reactor.

甲烷（DRM）的干重整使用甲烷（CH ₄）和二氧化碳（CO ₂）作为生产合成气的原料，具有独特的经济和环境效益。然而，DRM反应仍然面临催化剂烧结失活和碳形成的缺点。本文综述了不同DRM催化体系的研究进展。讨论了常规的单独催化系统，等离子催化系统和其他一些催化系统。给出了影响传统催化剂体系中催化剂性能评价的关键因素。特别地，等离子体催化系统是否可以实现比常规的单独催化系统更高的转化率已成为关注的焦点。因此，讨论了反应器的结构，排放方式以及与催化剂的结合。通过文献综述讨论了等离子体-催化剂相互作用的机理。此外，还考虑了DRM等离子催化系统的其他应用可能性。最后，比较了传统的单催化系统和等离子催化系统的优缺点。还引入了其他一些催化系统，例如催化膜反应器和太阳能驱动的甲烷重整。考虑到DRM的研究现状，可以通过改进DRM催化剂和优化等离子体反应器的设计来进一步提高转化率和能量转化效率。还引入了其他一些催化系统，例如催化膜反应器和太阳能驱动的甲烷重整。考虑到DRM的研究现状，可以通过改进DRM催化剂和优化等离子体反应器的设计来进一步提高转化率和能量转化效率。还引入了其他一些催化系统，例如催化膜反应器和太阳能驱动的甲烷重整。考虑到DRM的研究现状，可以通过改进DRM催化剂和优化等离子体反应器的设计来进一步提高转化率和能量转化效率。
