✦ Synopsis
The photosynthetic reaction of gas phase water and carbon dioxide molecules adsorbed onto strontium titanate surfaces that are in contact with platinum foiis is reported. The do xuiuant reaction product detected at 15 ton partial pressures of the reactant gases is methane-The reaction tikes g&ace without ar.y externally applied potential (between the foil and SrTi@) and in the absence of liquid electrolyte. when the &an, reduced SrTiOs ( 111) crystal face is ilhminated with Ii&t of energy gezrerttmtthe bandgapAthermalpro-,~~producesme'rhane,~entheSr~~--Pt~dwichisheatedin CO, and water, is also observed. The photo and thermal processes are ca.siIy distiguishcd by the use of filters.
