Reduced carbon and nitrogen compounds are atractive as storage forms of hydrogen and as readily useful sources of renewable energy. Fossil carbon resources are reduced carbon compounds produced during geochemical processes from carbon and nitrogen compounds of the biosphere. Using photoelectrochemical and photocatalytic reactions of semiconductors with carbon dioxide and carbonate, it iss possible to produce organic compounds such as formic acid, formaldehyde, methanol, acetaldehyde and ethanol. With nitrogen oxyanions such as nitrate and nitrite, similar reactions result in the production of hydroxylamine and ammonia. The reactions considered in the present work are the reduction of dinitrogen to ammonia, the cathodic reduction step from the nitrate ion through nitrite to ammonia, as well as the reduction of carbon dioxide.
