Recent Advances in the Application of Perovskite Catalysts in the Dry Reforming of Methane

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvantages of carbon deposition and sintering, so a highly efficient and robust catalyst with superior anti-deactivation properties is required. One way to meet this need is to incorporate active metals into crystalline oxides, such as perovskite. In this paper, recent advances in the application of perovskite catalysts in DRM are summarized, with particular attention paid to enhancing interfacial interaction, oxygen vacancies, and surface basicity. The structure-performance relationship is also discussed in depth.
