中文摘要：

象 perovskite 一样氧化物 La_(2-x ) Sr_xMO_4 上的 CH_4 和公司氧化反应(0.0 【=x【=1.0； M = Cu ， Ni )从循环伏安法方法被调查，发现那 forsuprafacial 公司氧化反应，催化剂活动有靠近的关联到在循环伏安法测量的氧化还原作用山峰的区域，山峰区域越大，活动将是越多 higher ，当时为界面的 CH_4 氧化反应，这项活动在氧化还原电位(三角 openE )主要取决于差别，并且在氧化还原电位的差别越小，活动将是越多 higher 。

英文摘要：

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.
