Research
To date, our research group has focused on the fabrication, modification, characterization and performance assessment of innovative electrode materials as well as testing of commercially-available electrodes. In particular, for electrochemical oxidation and electro-Fenton system, we have used different kinds of materials, like platinum, FTO and BDD as anodes and carbon cloth, nickel, carbon foam and carbon fiber brush coated with graphene, among others, as cathode materials. Currently, we are carrying out the scale-up of reactors for electro-Fenton, anodic oxidation and electro-coagulation processes, in order to have a practical industrial approach application.
