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

ABSTRACT: Although enormous progress has been made in C1 chemistry and CO2 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 H2O to liquid fuels (i.e., liquid hydrocarbons) at low temperature (?200?°C) in aqueous phase (i.e., in a benign solvent), in which H2O 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-Mo2C/C?+?Ru/C, which can directly convert CO and H2O in aqueous phase to liquid hydrocarbons with a production rate of 8.7 mol-CH2- molRu-1 h-1 and selectivity up to 68.4% of C5+ hydrocarbons at 200?°C.
