Zirconium oxide is active for photoreduction of gaseous carbon dioxide to carbon monoxide with hydrogen. A stable surface species arises under the photoreduction of CO2 on zirconium oxide, and it is identified as surface formate by infrared spectroscopy. Adsorbed CO2 is converted to formate by photoreaction with hydrogen. The surface formate is a true reaction intermediate since CO is formed by the photoreaction of formate and CO2; surface formate works as a reductant of carbon dioxide to yield carbon monoxide. The dependence on the wavelength of irradiation light shows that a bulk ZrO2 is not a photoactive species. When ZrO2 adsorbs CO2 a new band appears in photoluminescence excitation spectrum. The photoactive species in the reaction that CO2+H2 yields HCOO− is presumably formed by the adsorption of CO2 on ZrO2 surface. Hydrogen molecules play a role to supply an atomic hydrogen. Therefore, methane molecules can also be used as a reductant of carbon dioxide.
