Reduction of CO 2 to useful chemicals such as carbon monoxide, oxalic acid, and methanol has recently attracted considerable attention because of its decisive roles in the climate change and energy cycle. Here, Pt@nitrogen doped reduced graphene oxide (Pt@rNGO) is introduced as a new catalyst effective in the direct production of methanol from the reduction of CO 2 at various potentials and pH levels. The electrolytic reduction of CO 2 in a CO 2 saturated solution at a Pt@rNGO modified glassy carbon electrode is achieved under the optimum conditions of an applied potential of-0.30 V (vs. Ag/AgCl) and a pH equal to 2.0. The methanol thus produced is monitored by 13 C-NMR. The Faradic efficiency of the methanol production is found to be 41%. Results reveal that, compared to its counterparts used in previous studies, Pt@rNGO as a heterogeneous electrocatalyst requires a lower applied reduction potential and serves as a direct pathway for the conversion of carbon dioxide to methanol.
