Thermo-catalytic CO2 hydrogenation with renewable energy-powered green H2 is one of the most promising approaches for simultaneously producing fuels and chemicals (i.e., syngas, alcohol, and olefins,) and achieve a circular carbon economy. In order to successfully deploy commercial-scale CO2 hydrogenation, numerous investigations have been conducted on synthesis of high-performance catalysts. The carbon-based catalysts with certain functionalization treatments have superior properties for achieving excellent CO2 hydrogenation. Based on existing research findings, it is necessary to summarize the latest developments in the field of thermo-catalytic CO2 hydrogenation for significantly contribute to the ongoing research and development in this vital area. In this review, we addressed current advances in the fabrication of carbon-based catalysts for CO2 hydrogenation with representatives of porous carbon (PC), carbon nanotubes (CNTs), graphene, and metal–organic frameworks (MOFs) derived carbon materials. Detailed comprehensive assessments of carbon-based catalysts for CO2 hydrogenation, involving the properties of support and metal, catalytic activity and selectivity, and their interactions were systematically discussed. Finally, future challenges and research trends in the development of carbon-based catalysts for commercial-scale CO2 hydrogenation were addressed, shedding valuable lights on circular carbon economy and achieving UN Sustainable Development Goals including Goals 7, 12, and 13.
