Ambient pressure x-ray photoelectron spectroscopy (APXPS) can provide a compelling platform for studying an analyte's oxidation and reduction reactions in solutions. This paper presents proof-of-principle operando measurements of a model organometallic complex, iron hexacyanide, in an aqueous solution using the dip-and-pull technique. The data demonstrates that the electrochemically active liquid meniscuses on the working electrodes can undergo controlled redox reactions which were observed using APXPS. A detailed discussion of several critical experimental considerations is included as guidance for anyone undertaking comparable experiments.
常压 X 射线光电子能谱（APXPS）可为研究分析物在溶液中的氧化还原反应提供极具吸引力的平台。本文通过浸拉技术，使用模型有机金属配合物六氰合铁在水溶液中进行了原理验证的原位测量。数据表明，工作电极上的电化学活性液体弯月面可以进行受控的氧化还原反应，这可以使用 APXPS 进行观察。本文还包括了对几个关键实验考虑因素的详细讨论，为进行类似实验的人员提供了指导。
