Abstract
Converting methane and carbon dioxide into hydrogen and carbon monoxide is significant and attractive because it can mitigate the greenhouse effect and produce useful chemical intermediate. However, these two greenhouse gases are challenging to convert due to their high bond energy and chemically inert. Although thermocatalytic dry reforming of methane (DRM) achieves high efficiency, it requires high energy and often causes deactivation due to carbon deposition. Recently, a lot of research results show that photo-enhanced DRM is a promising and green route for this reaction under relatively mild conditions. This review first introduces the importance and challenge of CH4 and CO2 conversion. Then, we summarize the related reports of photo-enhanced dry reforming of methane in detail, including material preparation, experimental conditions and results, and mechanism study. In particular, the related studies have been classified according to types of input energy and the types of catalyst. Finally, we provide insightful perspectives and prospects for the future development of this field.
