In recent decades, growing CO2 in the Earth's atmosphere has become a major issue.

Thus, it is crucial to reduce the level of concentration of CO2 in the atmosphere.

We have investigated the adsorption and reduction of CO2 on metal-doped graphene sheets, through computational methods. The electrochemical reduction of CO2 to CO, CH3OH and CH4 were calculated. Co-doped graphene sheet shows very promising catalytic behavior for CO2 reduction with the highest elemental reaction energy less than 0.7 eV. In addition, tThe reaction pathways reveal the possible rate limiting step could be the removal of the second H2O, CH3OH or CH4 from the doped graphene sheet, depending upon the type of dopant in graphene.
