520 3 _aPhoto-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-reduction of CO2 were examined. The sol-gel method used for Al2O3-TiO2 catalysts preparation was also reported. The result shows for both solvents which are H2O and NaOH were able to react with CO2 to concentration methanol. Somehow, solubility of CO2 in NaOH is rather higher than H2O to concentration the methanol. The result analysed shown that the concentration of methanol in both NaOH and H2O were increasing with time. Somehow, the application of NaOH as solvent has shown better result compared to H2O where the concentration of methanol in NaOH was always greater than H2O for every time elapsed. The highest concentration of methanol in NaOH was 63 ng/µL while 43 ng/µL in H2O. Meanwhile, the effectiveness of temperatures shown the highest concentration of methanol was found at T= 60 oC. Since the boiling point of methanol is 65 oC, the production of methanol was limited. The liquid phase of methanol has changed to vapour phase which leads to the concentration of methanol was maximized within the ranges of temperatures as analyzed.
