Zinc oxide-Iron-Aluminum nanostructured cover for photoelectrochemical water splitting

  • L. Arriaga-Arjona (a1) and G. Carbajal-Franco (a1)


The purpose of this research is to study the viability of photocatalytic water splitting using ASTM A792 Zn-Al-Fe commercial metallic sheets as substrates for electrodeposited and corroded electrodes. The nanostructures were synthesized in two different procedures: via electrodeposition of migrating species from one electrode to another and from the remaining materials after corrosion of electrodes during electrodeposition, both procedures were done immersing the metallic electrodes in FeCl3 salts dissolved in water as cell electrolyte. The released or remaining Zinc-Aluminum-Iron can be used for the construction of nanostructures or as co-catalyst on the coating over the substrate. Actual EDS-SEM data reveals incorporation of Zinc on dendrite-like structures with traces of Al-Fe due to material release and further electrodeposition on working electrode, meanwhile, dendrite-like structures with an increased amount of Iron were obtained from the corrosion in the auxiliary electrode. Finally, samples were tested with lineal voltammetry to measure the photocurrent activity as indicator of photocatalytic viability for water splitting, obtaining an improvement of 31 mA/cm2 over natural photovoltaic current generation of substrates with higher Zinc concentrations under UV-Visible radiation.
