The production, characterization, and use of TiO2 nanotubes will be carried out in aqueous and organic mediums, to use them as photoanodes or substrates for the deposition of the ²-PbO2 and SnO2-Sb oxides by different techniques. Additionally, reticulated vitreous carbon substrates will be used for the deposition of the ²-PbO2 and possibly SnO2-Sb oxides. All these anodes will be applied in the photooxidation, electrophotooxidation and electrooxidation of organic pollutants. The use of TiO2 nanotubes in the photooxidation process will be carried out after a heat treatment in a microwave oven to obtain the oxide in the anatase crystallographic phase. Moreover, a new electrode material, amorphous carbon nitride, will be characterized and possibly used in the photooxidation of organic pollutants. The performances of the studied electrodes will be compared with the ones of boron-doped diamond electrodes.
