Ionic liquids (ILs) are considered to be potential material devices for CO2 capturing and conversion energy-adducts. They form a cage (confined-space) around the catalyst providing an ionic nano-container environment which serves as physical-chemical barrier that selectively controls diffusion of reactants, intermediates, products catalytic active sites via their hydrophobicity contact ion pairs. Hence, electronic properties catalysts in ILs can tuned by proper choice IL-cations anions strongly influence residence time/diffusion nano-environment. On other hand, provide driving force towards photocatalytic redox process increase photoreduction. By combining with semiconductor, unique solid semiconductor-liquid commodities generated lower activation energy modulating semiconductor surface. This mini-review provides brief overview recent advances IL assisted thermal hydrocarbons, formic acid, methanol, dimethyl carbonate, cyclic carbonates well its photo-conversion solar fuels.
