The use of electrochemistry in the synthesis of new materials with optimized properties is a low cost, fast and versatile methodology that has been studied for many years. Different types of materials have been developed, such as metals and their alloys, metallic heterostructures, oxide films, and conductive polymers. In other words, practically any type of material can be produced with advantages using electrochemical tools. In addition, the electrochemical study of phenomena occurring associated with a second source of energy, such as light, known as photoelectrochemistry, is quite common. Less common, but already well studied, is the coupling of the electric field with ultrasound, sonoelectrochemistry, and with an applied external magnetic field, magnetoelectrochemistry. The results obtained are always different from those obtained with only the use of the electric field. In this thesis project, the coupling of an electrochemical experiment with the microwave radiation for the synthesis of new electrode materials or even to study the redox reaction in solution will be investigated. In the first stage of the work it will be explored the fundamental aspects of the problem using computational methods such as the finite element method. Once we have characterized which are the main differentiators of the coupling of these two energy sources, we will study their applications in the synthesis of different functional materials and in electrocatalytic reactions. In this sense, the formation of oxide film on metallic niobium, chromium and steel, and, the electrodeposition of Ni and Cu alloys will be investigated. Finally, we will study the electrosynthesis of organic compounds with high added value and the oxidation of short chain alcohols. (AU)
