Synergy effect of CuO on CuCo2O4 for methane catalytic combustion

CuO and CuCo 2 O 4 exhibit a synergistic effect in catalyzing methane combustion, which increases the oxidation rate of methane on the surface of (CuO) 0.2 –CuCo 2 O 4 composite oxide and decreasing the methane combustion temperature.
