Abstract:

Antimony doped tin dioxide coated electrodes (Ti/SnO2-Sb2O5) on Ti substrates were prepared by the brush coating thermal decomposition method. Preparation conditions, structure, electrochemical characterization and service life of Ti/SnO2-Sb2O5 electrodes were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), cyclic voltammetry (CV) and accelerated life test methods. Results show that Ti/SnO2-Sb2O5 electrodes have a dry cracked-mud coating structure. A Ti/SnO2-Sb2O5 electrode coating prepared at an annealing temperature of 550 ℃ and with a molar ratio of nSn:nSb=9:1 for the precursor solution has a flat and compact surface, few cracks, low porosity, and good stability.
