  • Method to reduce COto CO using plasmon-enhanced photocatalysis
    Patent number: 9738529
    Abstract: Described is a method of reducing CO2 to CO using visible radiation and plasmonic photocatalysts. The method includes contacting CO2 with a catalyst, in the presence of H2, wherein the catalyst has plasmonic photocatalytic reductive activity when exposed to radiation having a wavelength between 380 nm and 780 nm. The catalyst, CO2, and H2 are exposed to non-coherent radiation having a wavelength between 380 nm and 780 nm such that the catalyst undergoes surface plasmon resonance. The surface plasmon resonance increases the rate of CO2 reduction to CO as compared to the rate of CO2 reduction to CO without surface plasmon resonance in the catalyst.
