“…Particularly interesting for this cell are electrodes embedded in PTFE or PEEK, as the electrochemical response will come only from the noncovered part at the top of the electrode (it will be thoroughly discussed in the next sections). Vitreous carbon electrodes, which are relatively inert for several applications, are useful as a 7; chamber for the electrolyte, the CE and the RE (8); electrolyte inlet and outlet (9,11,13), WE inlet (10); RE inlet (12); RE (14); CE inlet (15); bolt (18); SEC body -part 2 (19); WE (20). support of a myriad of electroactive materials, for example, nanoparticles made of metals or semiconductors.…”

“…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][26][27] In Situ Ultrafast Spectroscopy Figure 5 shows the SEC positioned in front of two femtosecond lasers in a homemade setup for measurements involving ultrafast spectroscopy. [29,30] The cell is the same used for Raman, but it is positioned like in the XAFS experiment, i. e., parallel to the bench.…”

[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.

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.

I am a researcher at CINE (Center for Innovation on New Energies), a new center created by FAPESP and Shell. The aim of our project is to design advanced materials for the generation of Dense Energy Carriers by using (photo)electrochemical processes. In this context, it is mandatory to understand the processes occurring at the electrode-electrolyte interface during the (photo)electrochemical reactions and the best way to get this information is by applying in situ techniques.
