Influence of Preparation Conditions of Sb-SnO_2 Interlayers on Characteristics of Ti/Sb-SnO_2/PbO_2 Anodes

摘要

Ti-based PbO_2 electrodes with Sb-SnO_2 interlayers were prepared by thermal decomposition. The effects of calcination temperature and Sb content of the Sb-SnO_2 interlayer on the service life and microstructural characteristics of the Ti/Sb-SnO_2/PbO_2 anodes were investigated. The results show that the Ti-based PbO_2 electrodes without the Sb-SnO_2 interlayer, Ti/PbO_2 electrodes, are rapidly deactivated at the experiment conditions, while the service life of the Ti/Sb-SnO_2/PbO_2 electrodes increases remarkably. Calcination temperature and Sb content for preparing the Sb-SnO_2 interlayer exhibit remarkable effects on the service life of the Ti/Sb-SnO_2/PbO_2 anodes.
