In this work the performances of N doped CuO-TiO<inf>2</inf> photocatalysts in gas phase CO<inf>2</inf> reduction have been studied. We have focused the attention on both the catalysts design and the process optimization. We have investigated, in particular, the effect of the presence of nitrogen and copper amount on the final catalysts performances. In order to learn high control of the catalytic process and to manage productivity and selectivity, by operating in very mild reaction conditions, the last part of the work has been centered on tuning the process parameters (CO<inf>2</inf>/H<inf>2</inf>O ratio). It has been observed that the CH<inf>4</inf> formation is sensitive to copper amount and that exists a close correlation between the catalytic behavior and the reagents ratio.

Abstract
Economic development should not be separated from the concept of sustainability. The goal can be pursued by means of technologically advanced materials and processes that enable environmental protection. Carbon dioxide photoreduction using water as reducing agent could be a green and effective way to pursue this aim and titania is a good photocatalyst for this reaction.
