Preparation and characterization of carbon fiber/graphite substrate NiHCF composite electrodes for electrochemically controlled ion separation

在碳纤维/石墨基体上通过毛细化学沉积法制备出具有高离子交换容量与高稳定性的铁氰化镍(nickel hexacyanoferrate,NiHCF)薄膜电极.采用循环伏安法考察了在石墨颗粒粒径100μm、PTFE含量0.05g/g石墨、乙醇量4ml/g石墨、制膜液浓度0.1mol/L(含1.07mol/L乙醇)条件下得到碳纤维/石墨基膜电极的离子交换容量、循环寿命与再生能力;并通过SEM、XPS分析了膜电极表面形貌、组成.研究结果表明,此多孔石墨基体电极比表面积大,沉积得到的NiHCF膜具有较大的离子分离能力、良好的循环稳定性与再生能力,可用于电化学控制离子分离(electrochemically controlled ion separation, ECIS)过程.
