The catalytic activity for CH_4 and CO oxidation of LaMO_3 (M is transition metal ion) perovskite-type oxide prepared by coprecipitation and mixing methods has been studied by activity evaluation, magnetic measurement, element analysis, TPE, TPSE and XED.

• 我们用活性评价、磁性测定、原子吸收光谱、TPR(程序升温还原)、TPSR(程序升温表面反应)、XRD等手段研究了以共沉淀和混合法制备的LaMO_3(M为从钛到铜的八个过渡金属离子)钙钛矿型化合物对GH_4和CO的催化氧化性能.
