| Abstract: | The electrodeposition of β PbO 2 on Ti and ceramic base electrode was studied, and the factors effecting the electrode lifetime, including additives of HF、Cu(NO 3) 2、Fe(NO 3) 3、Mn(NO 3) 2、PTFE and HNO 3, temperature, current density and current wave pattern were investigated as well. The experimental results showed that the ceramics based β PbO 2 electrode exhibited superior overall properties compared with Ti based electrodes. Under the current density of 100A/dm 2, the lifetime was up to 1300 h in 9 mol/L H 2SO 4 electrolyte solution. |
