Abstract: Numerous catalytic conversion technologies of greenhouse gases (GHG) such as CO2 and CH4 have been reported to produce economically feasible clean H2 fuel and syngas with desirable H2/CO ratio to modulate greenhouse gases emission from fossil fuel utilizations. The typical and commercially available catalytic conversions of GHG can be categorized with combined steam and CO2 reforming of methane (CSCR) having the characteristics of adjusted H2/CO ratio for further COx hydrogenation, dry reforming of methane (DRM) with severe coke deposition natures, and steam reforming of methane (SRM) or various organic compounds such as methanol, ethanol, acetic acid or biomass-derived resources to efficiently produce H2 fuel. The roles of heterogeneous catalysts are crucial in terms of catalytic activity and stability, and thermal catalytic reforming processes with those heterogeneous catalysts are regarded as economically feasible pathways for the commercialization of reforming reaction of GHG. Therefore, it seems to be required to grasp the properties and recent trends of the reported heterogeneous reforming catalysts for the conversions of CH4 and CO2 as representative greenhouse gases with feasible syngas or H2 production through thermal reforming reactions.
