研究了 L a1-x Srx Co1-x Bx O3 (B=Fe,Ni,Cr)复合氧化物催化剂催化 CO氧化活性 ,并通过氧的程序升温热脱附 (TPD)研究了该类催化剂的表面氧 ,结合活性与表面氧随 x的变化规律讨论了表面活性氧种
The activity of CO oxidation catalyzed by L a1-x Srx Co1-x Bx O3 (B = Fe, Ni, Cr) composite oxide catalysts was investigated. The surface oxygen of these catalysts was investigated by temperature programmed desorption (TPD) , The binding activity and the variation of surface oxygen with x were discussed
