Based on the latest research progress on dry reforming of methane and carbon dioxide,the strategies for methane activation are reviewed,namely adding metal additives and regulating the interaction between metal and support.The influences of the activated sites of carbon dioxide,including active metal particle size,alkaline sites and oxygen vacancies,on the adsorption and dissociation of carbon dioxide are summarized.The latest development of coupling between two active sites is overviewed,and the development of DRM catalysts is summarized.
