Ba-Pb-O和Bi-Pb-O的电化学合成和表征

Abstract

本文研究了用电化学方法在水溶液中合成铅基氧化物Ｂａ－Ｐｂ－Ｏ和Ｂｉ－Ｐｂ－Ｏ的方法，并采用ＸＰＳ，ＸＲＤ和ＥＤＸ对电合成产物进行了表征

Pb based oxides Ba Pb O and Bi Pb O were synthesized from aqueous solutions by using electrochemical method. The resulting Ba Pb O and Bi Pb O were characterized using XPS, EDX and XRD. The results show that perovskite BaPb 0.9 O 3 can be electrodeposited on the anode only from strong alkaline solution. In acid aqueous solution, conducting BiPb 2O z oxide is fromed on the anode. In these oxides the nominal valence of lead is +4.
