Effect of Solvents and Temperatures on Photo-Reduction of Carbon Dioxide Using Alumina Doped Tio2 Catalysts

Photo-reduction is the most promising method to reduce carbon dioxide to a valuable product such as methanol. Apart of a simple process, photo-reduction also has a great potential to become a method for renewable energy in the future. In this study, the effects of solvents and temperatures in photo-...
