我们建议，火焰的电离气体介质可能是一个合适的介质，在其中可以研究电化学现象。本通讯包含了对气相电化学现象的初步研究，通过考虑作为电解质的火焰介质。提出了一个假设，这可能解释了发生的电化学电位建立在金属电极表面插入火焰时。使用循环伏安法与三电极系统，我们观察到电流的步骤，我们已经解释为法拉第还原铁和铜离子引入火焰。虽然这里提出的解释是在这个阶段的推测，结果开辟了新的途径，电化学的研究和应用，提出电离气体介质作为车辆的气相电化学。
We propose that the ionised gaseous media of a flame may be a suitable medium in which electrochemical phenomena can be investigated. This communication contains preliminary investigations into electrochemical phenomena in the gas phase, by considering the media of a flame as an electrolyte. A hypothesis is presented which possibly explains the occurrence of an electrochemical potential established at a metallic electrode surface when inserted into the flame. Using cyclic voltammetry with a three-electrode system, we observe current steps, which we have interpreted as Faradaic reduction of iron and copper ions introduced into the flame. Although the interpretations presented here are at this stage speculative, the results open new avenues for research and applications of electrochemistry by proposing ionised gaseous media as vehicles for gas phase electrochemistry.
