Abstract

The present proposal research aims to develop fundamental studies of electrocatalytic processes by means of Raman spectroscopy in situ technique, usually called as EC-SERS. Raman spectroscopy is a well-established vibration spectroscopy technique due to its high specificity and sensitivity, especially with the aid of the SERS effect, has been widely used in electrochemistry to determine qualitative and quantitative molecular information of almost any type of sample, whether solid, liquid or gas. The design of a EC-SERS technique can be divided in two fundamental parts: (a) development of the electrochemical system coupled to a commercial confocal microscope and (b) application of the technique in the study during the oxidation of small molecules processes on the interface electrode/solution and consequently vibrational disturbances caused by electric field applied externally, particularly we will focus our attention to the study of the electrocatalytic oxidation reaction of polyols on gold and silver surfaces.
