| 摘 要： | 用机械合金化法合成了Mg0.9Ti0.1Ni0.9X0.1(X=Mn,Zn,Co,Fe)系列合金.X射线衍射(XRD)结构分析表明,用X部分替代Ni后,促进了Mg0.9Ti0.1Ni合金的非晶化过程.用Co和Fe部分替代Ni提高了合金的放电容量,但却降低了合金的循环稳定性.用Zn和Mn部分替代Ni提高了合金电极的循环寿命,尤其是Mg0.9Ti0.1Ni0.9Zn0.1合金电极经10个充放电循环后,其放电容量仍可达到313.8mA.h/g.对添加Co后的合金进行p-c-T测试发现,Mg0.9Ti0.1Ni0.9Co0.1合金的吸放氢容量明显比Mg0.9Ti0.1Ni合金高,这与电化学所测到的结果一致.

| Abstract: | The degradation of Microcystins(MC-RR, MC-LR) via electro-Fenton reaction using the activated carbon fiber(ACF) felt cathode with a large surface area was experimentally investigated. The effect of applied current, initial pH values of solution and Fe+{2+} ion concentration were discussed in detail. The results show that 75% of MC-RR and 94% MC-LR were eliminated after 60 min electrolysis under the operation conditions of 6.6 mA/cm+2 current density, 1.0 mmol/L Fe+{2+} at pH=3. The results indicate that H-2O-2 could be effectively electrogenerated from O-2 reduction on the ACF felt cathode and microcystins could be rapidly eliminated. |
