In this study, a gas-phase photocatalytic CO2 reduction to CH4 using a anionic porous Zn-metalated porphyrin metal-organic framework (MOF) induced by an ionic liquid was presented. The MOF catalyst exhibited strong CO2 affinity and a favorable conduction band position, enabling high selectivity (around 70%) for CO2 to CH4 conversion in H2O vapor.
Presented here are the synthesis and gas-phase photocatalytic CO2 reduction of an anionic porous Zn-metalated porphyrin metal-organic framework (MOF) induced by an ionic liquid. The desired CO2 affinity and deep conduction band position of the MOF catalyst provide strong kinetic and thermodynamic advantages for photocatalytic CO2 to CH4 conversion with high selectivity (similar to 70%) in H2O vapor.
