氧化还原体系K4Fe(CN)6吸附于阴离子交换剂颗粒(Dowex1×2,直径通常为200 µm),并浸渍1-丁基-3-甲基咪唑四氟硼酸盐离子液体(BMIM+BF4−),与直径50 µm的铂微电极接触,表现出良好的Fe(III/II)伏安响应。在干气或相对湿度为80 %的Ar气流存在下,研究了离子液体球-电极-气体界面上的过程。由于Bmin+BF4的吸湿特性,−电流对湿度水平很敏感。脉冲和连续的微波激活(2.45 GHz)被证明是由于微波能量的聚焦而在铂微电极尖端局部发生的。阻抗实验表明存在一层薄的离子液体活性膜。
The redox system K4Fe(CN)6adsorbed into anion exchanger particles (Dowex 1×2 of typically 200 µm diameter) and impregnated with 1‐butyl‐3‐methyl‐imidazolium tetrafluoroborate ionic liquid (BMIM+BF4−) in contact to a 50 µm diameter platinum microelectrode show well‐defined Fe(III/II) voltammetric responses. Processes are studied at the ionic liquid sphere | electrode | gas interface in the presence of dry or 80 % relative humidity argon gas flow. Due to the hygroscopic nature of BMIN+BF4−currents are sensitive to humidity levels. Pulsed and continuous microwave activation (2.45 GHz) is shown to occur locally at the tip of the platinum microelectrode due to focusing of microwave energy. Impedance experiments reveal the presence of a thin active film of ionic liquid.
