Abstract
Material of CeMg mixed oxide nanoparticle doping with Ni metal can be applied as catalyst for CO oxidation reaction. It was successfully synthesized by macromolecule surfactant modified method and characterized by XRD, BET, and TEM–EDX techniques. Both alkaline-earth (Mg2+) and transition metal (Ni2+) doped into CeO2 entered the lattice of CeO2 to form a solid solution of CeMgO and CeMgNiO, respectively. Ni doping on CeMg mixed oxide showed much better activity of CO oxidation compared to CeMg mixed oxide itself.
