[Preparation and electro-catalytic characterization on La/Ce doped Ti-base lead dioxide electrodes].
Huan Jing Ke Xue. 2012 Mar; 33(3):857-65.HJ

Abstract

Ti-base lead dioxide electrodes (Ti/PbO2) doped with rare earth La, Ce were prepared by the electrode position. The surface morphology and crystal structure of the electrodes was analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD), the results showed that, microstructure and crystal orientation of electrode surface changed after doping rare earth La, Ce, which made the electrode surface more dense and uniform. The electrochemical properties of the electrodes were tested by linear sweeping (LS) and cyclic voltammogram (CV), the experimental results show that, La, Ce doping improved the electrode overpotential of oxygen evolution and the peak current density, promoted the catalytic performance of the electrode. Different doping amount of modified electrodes were used to degrade methylene blue simulative dyeing wastewater, the results showed that, electrodes doped La and Ce respectively 8.0 g x L(-1) and 5.0 g x L(-1) have the best degradation efficiency and catalytic activity, for example, the removal of MB and its COD respectively researches 83.85%, 79.95% and 79.18%, 76.21%. The possible degradation pathways and mechanisms were also discussed.
