Global CO2 Recycling Through Methanation Reaction Using Neodymium Doped Nickel Oxide Catalyst

Methanation reaction using nickel oxide and neodymium doped nickel oxide based catalyst was studied. Doping nickel oxide with neodymium results in higher catalytic activity than a pure nickel oxide catalyst with 100% methanation of CO2 at a low temperature of 350oC. Characterization of the neodymium doped nickel oxide by a XRD, SEM and nitrogen gas adsorption suggested that a small portion of the catalyst showed amorphous properties and that the small sized particles of this catalyst may contribute to the high catalytic activity.
