Assessment of MoTiO۳/GO Integrated Photocatalyst for Converting CO۲ to Methanol

In this study, the citric acid-assisted sol-gel method was used for perovskite MoTiO۳/GO nanocomposites preparation. The prepared samples were characterized by SEM, BET, FT-IR, and XRD analysis. The photocatalytic activity of MoTiO۳/GO was evaluated by converting CO۲ under visible light irradiation to methanol. Results indicated that MoTiO۳/GO (۱.۵wt.%) exhibited significant methanol production up to ۳۰۳.۷ µmol g cat-۱ after visible light irradiation lasting for ۴ hr.  Therefore, it can be said that MoTiO۳ / GO is a suitable candidate for the efficient conversion of CO۲ to methanol.
