Abstract
A method for the light driven photocatalytic reduction of carbon dioxide or the bicarbonate ion to one or more compounds which comprises contacting certain metal compounds with the carbon dioxide and/or bicarbonate ion in the absence of separate physical electrolyte and electrodes, and conducting said contacting in the presence of a reducing agent such as water and light.
Claims14
A method for the light driven photocatalytic reduction of carbon dioxide or the bicarbonate ion to at least one compound which comprises contacting at least one metal compound catalyst selected from the group consisting of of CoO, Co.sub.3 O.sub.4, Co.sub.2 O.sub.3, Cr.sub.2 O.sub.3, Cu.sub.2 O, CuO, La-Ni-oxide, platinized La-Ni-oxide, La.sub.2 O.sub.3, Nd.sub.2 O.sub.3, NiO, PbO, and mixtures and combinations thereof with at least one of carbon dioxide and the bicarbonate ion in the presence of a reducing agent and in the absence of other carbon sources and separate physical electrolyte and electrodes, and conducting said contacting in the presence of light so that the energy of reduction is essentially supplied by said light.
