Versatile Spectroelectrochemical Cell for in Situ Experiments: Development, Applications and Electrochemical Behavior
2020
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.
