The optimum ratio of Sb2O3 to SnO2 was 15%25%. Addition of NaF（0.40 g/L） in electroplating solution could decrease the rate of PbO2 deposition, which resulted in the formation of small crystal particles and compact PbO2 films. XRD study showed the β-form crystal of electrode. The electrode was tested in synthesis of 4-picoline acid by electro-oxidation of 4-picoline, showing good electroconductivity and stable life.展开更多
