Micro- and nanostructured TiO2 substrate. Influence on the electrocatalytic properties of manganese oxide based electrodes
Mixed ruthenium and manganese oxides electrodes (1:1 molar ratio) have been prepared by spin-coating deposition and subsequent thermal decomposition of a thin film on a titanium support. To improve both stability and adhesion of the coating, either micro- or nanomodification of the titanium surface has been investigated. The micro-modified support has been obtained by etching of the titanium foil with hydrofluoric acid (HF) while the modification at a nanoscale has been obtained by anodization of the titanium foil in a glycerol medium containing fluoride.
