principles, as shown in the case of 3D PbO 2 electrodeposited using biocompatible
methanesulfonic acid. Regarding the use of nanomaterials in hybrid processes,
adsorption with nanomaterials like Gr followed by EF or PEF post-treatments of
the resulting effluents is an interesting way worth exploring, which can be combined
with washing nanoadsorbents by means of Fenton-based EAOPs, as recently
addressed by some authors. Finally, it is worth mentioning that the tests of these
new materials and reactors should be carried out with real wastewater matrices in
order to correctly assess their viability when compared to robust separation technologies like adsorption, (electro)coagulation, or membrane separation. Reusability
tests in those complex matrices are thus needed to assess the impact of the catalyst
degradation on the treatment costs as well as the reproducibility upon successive
usage.
