Direct conversion of CO and H2O into liquid fuels under mild conditions

Although enormous progress has been made in C 1 chemistry and CO 2 conversion in recent years, it is still a challenge to develop new carbon resource transformation protocols especially those lead to the production of liquid fuels with high selectivity under mild conditions (e.g., under low temperat...

Description
Summary:Although enormous progress has been made in C 1 chemistry and CO 2 conversion in recent years, it is still a challenge to develop new carbon resource transformation protocols especially those lead to the production of liquid fuels with high selectivity under mild conditions (e.g., under low temperature and using benign solvent). Herein, we present a novel and energy-efficient catalytic route to directly transform CO and H 2 O to liquid fuels (i.e., liquid hydrocarbons) at low temperature (≤200 °C) in aqueous phase (i.e., in a benign solvent), in which H 2 O served as both hydrogen source and solvent for the liquid fuel production. The key to the catalytic process is the construction of a highly efficient tandem catalyst Pt-Mo 2 C/C + Ru/C, which can directly convert CO and H 2 O in aqueous phase to liquid hydrocarbons with a production rate of 8.7 mol -CH2- mol Ru −1 h −1 and selectivity up to 68.4% of C 5+ hydrocarbons at 200 °C. Developing new carbon resource transformation protocols leading to the production of liquid fuels with high selectivity under mild conditions remains challenging. Here the authors present a novel and energy-efficient catalytic route to directly transform CO and H 2 O to liquid fuels at low temperature in aqueous phase.
