Abstract:
The invention relates to a method for converting carbon dioxide to methane. The method comprises exposing carbon dioxide adsorbed on a nanoporous silicate matrix to light in the presence of a source of carbon dioxide and a source of hydrogen for a time and under conditions sufficient to convert carbon dioxide to methane. The matrix contains at least one photochromic metal oxide entity, and contains a Cimpurity site. The light has a wavelength of about 437 nm to about 1200 nm.
