Abstract

We report on various strategies for the synthesis of titania-based photocatalysts, including mixed phase titania, and anatase nanotubes. These photocatalysts have shown improved efficiency for the transformation of CO 2 to methane as tested in the absence of sacrificial hole scavengers. The EPR studies have revealed a high concentration of undercoordinated Ti atoms on the surface of photocatalysts that improve adsorption/binding of CO 2, and thus, the photoefficiency of the reaction.
