“…However, by changing the carbon vitreous bulk electrode to a hollow one (with carbon paper), the same cell can be used to measure in transmission mode, i. e., the beam will cross the window, pass along the SEC body and hit the detector located right behind the SEC. Alternatively, this same SEC can also be adapted to XRD in reflection mode or grazing incidence to perform measurements of GISAXS, XRR or CDI techniques using a mylar film as the window [1,25–27] …”

[a, b] (Photo)electrochemical processes are involved in many fields of science and technology. The use of spectroscopic techniques coupled to (photo)electrochemistry, are mandatory to get information about interfacial processes on scale ranges from millimeters to the nanoscale. The development of spectroelectrochemical cells (SECs) contributes to the progress of the field of (photo)electrochemistry and their impact in science and technology. Therefore, in this work, we describe in detail the development of a versatile SEC that can be used for conventional electrochemical experiments and several in situ techniques just by changing its window. We performed electrochemical and computational experiments to analyze the response of our SEC as a function of the working electrode size, position, and distance to the window. Besides, we show in detail how the cell can be used to perform experiments of in situ FTIR, Raman, XAFS and ultrafast spectroscopy.

“…When in situ/operando cannot be accomplished or the method is destructive, ex situ characterization can still be used, granted that special attention is paid to sample preparation and transfer from the electrochemical environment to the characterization tool. Given the number of review articles present in the literature focusing on characterization tools more broadly, − here we will list a range of methods as shown in Table , that are important for probing changes in composition, structure, and morphology. We separate the techniques into four broad classes, mass spectrometry, microscopy, spectroscopy, and crystallography, and highlight the benefits and unique information each method provides as well as some of their limitations.…”

The path toward a renewable energy future relies on the development of materials for electrochemical energy technologies that are not only highly functional but also stable. In this Perspective, we will discuss a framework for the relationships between function and stability, starting by revisiting how we measure stability that should focus on changes to the nature and number of active centers (materials stability) together with monitoring how current/potential change over time during operation (reaction durability). By shifting our focus to materials properties, we then discuss how subtractive and additive processes such as dissolution, deposition, and (de)intercalation contribute to changes in the local surface composition, coordination environment, and phase restructuring that accompany the degradation of electrochemical materials. Ultimately, gaining insights into the processes responsible for changes to active centers during operation will help us better predict and control the durability of materials for clean energy.

Abstract: (Photo)electrochemical processes are involved in many fields of science and technology. The use of spectroscopic techniques coupled to (photo)electrochemistry, are mandatory to get information about interfacial processes on scale ranges from millimeters to the nanoscale. The development of spectroelectrochemical cells (SEC) contribute to the progress of the field of (photo)electrochemistry and its impact in science and technology. Therefore, in this work, we describe in detail the development of a versatile SEC that can be used for several in situ techniques. We performed electrochemical and computational experiments to analyze the response of our SEC as a function of the working electrode size, position and distance to the window. We found that our SEC behaves as the conventional cell when the electrode is far from the window. However, important differences arise in the thin layer configuration. The computational experiments suggest that to mitigate these problems, it is important to perform in situ experiments in the thin layer configuration using electrodes as small as possible.
