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 (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. (AU)
