| 中文摘要: |
| 在不同温度和电流密度的条件下,制备不锈钢基PbO2 电极,分析了电极的析氧曲线及析氧动力学参数,进而考察了温度和电流密度对PbO2 电极节能性和电催化活性的影响。结果表明:温度为80℃,电流密度为30mA/cm2 时,制备的电极成分稳定,重现性好,可有效降低槽电压,电催化活性良好;在小电流密度下的主要产物为β-PbO2,大电流密度下生成部分α-PbO2;与传统的铅基阳极材料相比,该PbO2 电极节能性和催化活性均有较大程度的提高。 |

| Through the analysis of oxygen evolution curve and oxygen evolution kinetic parameters of PbO2 electrode on stainless steel substrate prepared by different temperature and different current density, the effect of temperature and current density on the energy saving property and catalytic activity of PbO2 electrode was studied. The results show that when the temperature is 80℃, current density is 30 mA/cm2, the electrode have a stable composition and good reproducibility, the cell voltage is decreased and have a good electro-catalytic activity; The mainly products are β-PbO2 at low current density and there are partial products are α-PbO2 at high current density; The energy saving property and catalytic activity are highly improved compared with the traditional Pb-Ag alloy anode. |
