title: Stability and deactivation research of RuO2-PdO/Ti electrode in dye water degradation.
abstract: RuO2-PdO/Ti electrode was prepared and used for the electro-catalytic degradation of Active Red K-2BP. It was found that the electrode was very stable in the process. A discoloration rate of 96.2% could still be achieved on the electrode after being used for 100 runs. X-ray photoelectron spectroscopy, X-ray diffraction, and scanning electron microscopy characterizations of the electrode were carried out. Results showed that the deactivation of the electrode was caused by the reconstruction and oxidation of titanium substrate as well as by the coverage of the active phases on the surface of the electrode by silicon. The cracks on the coating layer also contributed to the deactivation.
