Electro-Catalytic Properties Of Β-Pbo2/Sb-Sno2/Ti Electrode On Phenol Oxidation, Peng Li, Yue-Min Zhao, Li-Zhang Wang, Yan-Le Zhang, Zhao-Qing Lu

Journal of Electrochemistry

The combination technology of brush pyrolysis and electroplating was employed in the preparation of β-PbO₂/Sb-SnO₂/Ti electrode. X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) results showed that the Sb-SnO₂ as an interlayer would restrain the formation of lead fluoride and the crystallization degree on the electrode surface could be as high as 100%. The grain size was calculated by Scherrer formula to be 25.2 nm and the agglomeration of lead dioxide was effectively eliminated. The potential span of diffusion control phase, oxygen evolution potential, Tafel slope for the β-PbO₂/Sb-SnO₂/Ti electrode during …
