Directly converting CO2 into a gasoline fuel

Abstract

<jats:title>Abstract</jats:title><jats:p>The direct production of liquid fuels from CO<jats:sub>2</jats:sub> hydrogenation has attracted enormous interest for its significant roles in mitigating CO<jats:sub>2</jats:sub> emissions and reducing dependence on petrochemicals. Here we report a highly efficient, stable and multifunctional Na–Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub>/HZSM-5 catalyst, which can directly convert CO<jats:sub>2</jats:sub> to gasoline-range (C<jats:sub>5</jats:sub>–C<jats:sub>11</jats:sub>) hydrocarbons with selectivity up to 78% of all hydrocarbons while only 4% methane at a CO<jats:sub>2</jats:sub> conversion of 22% under industrial relevant conditions. It is achieved by a multifunctional catalyst providing three types of active sites (Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub>, Fe<jats:sub>5</jats:sub>C<jats:sub>2</jats:sub> and acid sites), which cooperatively catalyse a tandem reaction. More significantly, the appropriate proximity of three types of active sites plays a crucial role in the successive and synergetic catalytic conversion of CO<jats:sub>2</jats:sub> to gasoline. The multifunctional catalyst, exhibiting a remarkable stability for 1,000 h on stream, definitely has the potential to be a promising industrial catalyst for CO<jats:sub>2</jats:sub> utilization to liquid fuels.</jats:p>
