Impact of chemical composition of the substrate on the synthesis and behaviour of nano hard anodised layers

Fluorine‐Doped Tin Oxide/Alumina as Long‐Term Robust Conducting Support for Earth‐Abundant Water Oxidation Electrocatalysts

“…The electrochemical experiments were performed at room temperature and atmospheric pressure in half-cell configuration (See Figure S9 in Supplementary Information) by using a Biologic SP-150 potentiostat and a buffer electrolyte prepared in 50 mM KPi (pH 7) containing 1 M KNO 3 . A H-cell was used where the anode and cathode compartments were separated by a porous glass frit and all the experiments were carried out under magnetic stirring at c.a.…”

“…Moreover, this material is mechanically, chemically and thermally stable. AAO hardness, corrosion resistance and erosion resistance have shown to be improved after the aluminum anodization process . For instance, AAO is attractive as template or host material for the growth of ordered nanotube or nanowire arrays for electrochemical applications like energy storage and conversion .…”

“…AAO hardness, corrosion resistance and erosion resistance have shown to be improved after the aluminum anodization process. [3] For instance, AAO is attractive as template or host material for the growth of ordered nanotube or nanowire arrays for electrochemical applications like energy storage and conversion. [4] As a few examples, AAO templates have been used to fabricate a nanostructured CdS-CdTe solar cell [5] or a photoanode for water splitting based on Fe 2 TiO 5 nanotubes.…”

“…[6] In these cases the AAO support is removed after the deposition of the guest material leading to free-standing nanoporous structures. The AAO removal is typically performed by immersing the composite material into a concentrated NaOH or H 3 PO 4 solution. There are several examples of nanoporous electrodes obtained in this way which have been tested for different electrocatalytic reactions such as electroreduction of chloroform, [7] hydrogen evolution reaction, [8] electrooxidation of hydrazine, [9] urea, [10] methanol [11][12] or ethanol.…”
