乳酸在NiPTFE复合电极上的电氧化
摘要:
以镍为基材,恒电流阴极电镀Ni-PTFE(聚四氟乙烯)制得疏水性复合电极,测得镀层PTFE的质量分数为6.7%。将该电极应用于乳酸电氧化制备丙酮酸的研究,实验中测定了阳极极化曲线、循环伏安、电极稳定性等电化学特征,电氧化过程的电流效率为34%,乳酸的转化率可达72%,表明了Ni-PTFE复合电极对乳酸电氧化制备丙酮酸具有实际的应用价值。

Electrooxidation of Lactic Acid on Ni-PTFE Composite Electrode
Abstract:
Hydrophobic nickel-poly tetrafluoroethlyene(Ni-PTFE) composite electrode has been prepared by constant current and cathodic electroplating with nickel as substrate in a PTFE suspension. The Ni-PTFE electrode was used for electrooxidation of lactic acid to pyruvic acid. The electrochemical characterizations such as polarization curve, cyclic voltammogram and electrode stability have been carried out. The current efficiency of electrooxidation of the electrode with 6.7% mass fraction PTFE coating was 34% and the conversion ratio of electrooxidation of lactic acid was 72%.
