Converting CO2 from a detrimental greenhouse gas into value-added liquid fuels not only contributes to mitigating CO2 emissions,but also reduces dependence on petrochemicals.Unfortunately,the activation of CO2 and its hydrogenation to hydrocarbons or other alcohols are challenging tasks because CO2 is a fully oxidized,thermodynamically stable and chemically inert molecule.Most research to date,not surprisingly,is focusing on selective hydrogenation of CO2 to short-chain products,while few studies on long-chain hydrocarbons,such as gasoline-range (C5-C11) hydrocarbons.The key to this process is to search for a high efficient catalyst.
