Abstract

(Electro)catalysis is undoubtedly important because it involves relevant processes in several areas of science and technology. Catalyzed reactions are present in virtually all branches of chemistry, but are especially important in industrial applications, such as in the energy sector, in the development of fuel cells, in the transformation of low-cost molecules into dense energy carriers, and in the environmental sector, water and sewage treatment or remedies. In this project, we aim to study catalytic systems using Platinum electrodes using conventional electrochemical techniques coupled with the following characterization techniques: Kelvin microscopy (KPFM) and spectroscopy with femtosecond lasers in situ. Platinum is one of the main catalysts used, therefore, the study of the electrode-solution interface of surfaces based on this metal helps in understanding the various mechanisms involved during (electro)catalytic processes and, therefore, contributes with the necessary knowledge to improve them.
