Catalytic dry reforming of methane (DRM) is a promising way for renewable syngas production due to the utilization of both CO₂ and CH₄ greenhouse gases. Current approaches were made to improve the catalytic activity and coke resistance by introducing a second metal into the Ni‐based catalytic system. This bimetallic catalytic system showed a significant improvement in coke resistance due to the synergistic effect of both metals towards the reaction. This review summarizes recent developments in bimetallic catalysts in DRM which focused on the evaluation of catalysts, deactivation studies, and reaction mechanisms of developed bimetallic catalysts.

甲烷低温二氧化碳重整的高性能双金属催化剂

由于同时利用CO ₂和CH ₄温室气体，甲烷的催化干重整（DRM）是可再生合成气生产的一种有前途的方式。通过将第二种金属引入镍基催化体系中，目前已有方法来提高催化活性和抗焦性。由于两种金属对反应的协同作用，这种双金属催化体系显示出显着的耐焦化改进。这篇综述总结了DRM中双金属催化剂的最新进展，其重点是催化剂的评估，失活研究以及已开发的双金属催化剂的反应机理。
