Hydrogenation of carbon dioxide (CO₂) to synthesize fuels is one of the promising technologies for CO₂ capture, utilization and storage, and must be commercialized to achieve a carbon-neutral society.

Fisher-Tropsch synthesis (FTS) over cobalt-based catalyst is known to be efficient to produce fuels from syngas, that is carbon monoxide (CO) and hydrogen. However, in CO₂-FTS using CO₂ instead of CO, formation of methane is dominant in the reaction. Thus, CO₂-FTS is not industrialized yet.

In this research, the catalytic property of CO₂-FTS over alkali metal doped cobalt/silica catalyst was studied to realize CO₂ hydrogenation to produce C2+ hydrocarbons.
