Assessment of MoTiO3/GO Integrated Photocatalyst for Converting CO2 to Methanol

In this study, the citric acid-assisted sol-gel method was used for perovskite MoTiO3/GO nanocomposites preparation. The prepared samples were characterized by SEM, BET, FT-IR, and XRD analysis. The photocatalytic activity of MoTiO3/GO was evaluated by converting CO2 under visible light irradiation to methanol. Results indicated that MoTiO3/GO (1.5wt.%) exhibited significant methanol production up to 303.7 µmol g cat-1 after visible light irradiation lasting for 4 hr.  Therefore, it can be said that MoTiO3 / GO is a suitable candidate for the efficient conversion of CO2 to methanol.
