Paper Title:
Anodic Synthesis of α-PbO2-CeO2-TiO2 Composite Materials from Colloidal Electrolyte: Morphology, Composition and Structure of PbO2-Matrix Composites
  Abstract

During electrodepositing pure lead dioxide, the electrocatalytic activity of PbO2 electrodes, as well as their stability, can often be considerably enhanced by the incorporation of some fine particles added to the electrodeposition. The morphology, crystal phase, surface composition, microstructure, of the electrode were characterized by means of SEM, XRD and EDS. SEM-EDS analysis showed the addition of solid particles could inhibit the growth of α-PbO2 unit cells, improving the specific surface areas of coating surface.Under all condition, the matrix was highly oriented α-PbO2. The electrocatalytic activity of the prepared materials has been tested in Zn2+ 50g L-1, H2SO4 150g L-1 solution. It showed that the electrocatalytic activity of the A1/conductive coating/α-PbO2-3.71 wt.% TiO2-2.12 wt.% CeO2 anode is the best.
