 Carbon capture and utilization has been identified as a promising strategy to reduce greenhouse gas emissions and meet global energy and climate goals. In particular, catalytic hydrogenation of waste CO2 with renewable hydrogen can produce valuable chemical feedstocks and energy carriers. Fisher-Tropsch synthesis-based hydrocarbons have the potential to create a circular carbon economy with a significant reduction in anthropogenic emissions. Progress towards this goal has been made by developing catalysts based on cobalt oxide-supported structures which can convert CO2 into longer-chain hydrocarbons. These catalysts require careful control of the metal support interface, promoter selection, and reducible oxide supports to maximize activity and selectivity.
