Synthetic Boron-Doped Diamond Electrodes for Electrochemical Water Treatment

Boron-doped diamond electrodes have emerged as anodic material due to their high physical, chemical and electrochemical stability. These characteristics make it particularly interesting for electrochemical wastewater treatments and especially due to its high overpotential for the Oxygen Evolution Reaction. Diamond electrodes present the maximum efficiency in pollutant removal in water, just limited by diffusion-controlled electrochemical kinetics. Results are presented for the elimination of benzoic acid and for the electrochemical treatment of synthetic tannery wastewater. The results indicate that diamond electrodes exhibit the best performance for the removal of total phenols, COD, TOC, and colour.

Materiales carbonosos nanoestructurados para la preparación de catalizadores híbridos mediante el sistema SILP

The main objective of this Doctoral thesis is the preparation of hybrid active catalysts using the SILP (Supported Ionic Liquid Catalysis) methodology and employing carbon materials as support. For that, in first place, SILP samples have been prepared and characterized. In second place, hybrid the SILP catalysts have been prepared, characterized and tested in some hydrogenation reactions, including an asymmetric hydrogenation. The investigated variables are mainly the amount and kind of ionic liquid and the physical, chemical and morphological properties of the support.
