且通过XPS分析可知催化剂表面含有Bi、Co 和O等3种元素,其中Co存在Co2+和Co3+两种价态,且与其中的Bi存在Bi-Co相互作用,这将有利于增强催化剂的催化活性和稳定性;此外,催化剂中的O以晶格氧和表面羟基氧两种形式存在。

Changes in electronic structure of the Bi-O and Cu-O planes due to the simultaneous doping of Pb at the Bi site and Y at the Ca site in the Bi-2212 system have been studied using core-level photoemission. The rare-earth doping at the Ca site causes an increase in the valence state ...
