Abstract

The interlayer containing Mn element and the SnO₂ surface coating were prepared by dip coating and sol-gel method, respectively. The Ti/SnO₂ and Ti/MnO_x/SnO₂ electrode were prepared by thermal oxidation technique. The service life of electrodes was evaluated by accelerated life experiment under big current density. The micrographs of electrode surface, the element composition of different layers and the chemical environment of elements in electrode surface were analyzed with the help of SEM, EDS and XPS. It was found that Ti/MnO_x/SnO₂ electrode processed longer service life than that of Ti/SnO₂ electrode. The main reasons of long service life were compacted coating and much crystal oxygen in electrode surface which could reduce or resist the corrosion of electrode.
