CH4 and CO oxidation reaction on perovskite-like oxides La2-xSrxMO4 (0.0=x=1.0; M = Cu, Ni) was investigated from cyclic voltammetry method, finding that for suprafacial CO oxidation reaction, the catalyst activity has a close correlation to the area of redox peaks measured in the cyclic voltammetry, the larger the peak area is, the higher the activity will be, while for interfacial CH4 oxidation reaction, the activity depends mainly on the difference in redox potentials (?E), and the smaller the difference in redox potentials is, the higher the activity will be.
