Title:
METHOD FOR CARBON DIOXIDE METHANATION USING RH PLASMONIC PHOTOCATALYST
Document Type and Number:
WIPO Patent Application WO/2018/140326
Kind Code:
A3
Abstract:
A method for hydrogenating carbon dioxide to methane comprises providing a rhodium photocatalyst having rhodium nanoparticles on a metal oxide support, conditioning the rhodium photocatalyst, exposing the rhodium photocatalyst to hydrogen gas and carbon dioxide gas, and illuminating the rhodium photocatalyst with blue light or ultraviolet light. In some embodiments, the rhodium nanoparticles are in the form of nano-cubes and the intensity of illumination is sufficient to cause the reaction rate of methane to have a super-linear dependence on illumination intensity,
