The present invention relates to surface treatments of aluminum foils and aluminum foil alloys. The process for surface treatment includes steps of applying an etching solution to chemically etch at least one surface of the foil to form an etched surface, and forming an aluminium oxidized coating on the etched surface. The present invention also relates to a method of producing an immobilized transition metal nanofibre using an electrospinning apparatus having a spinning tip, the method including the steps of, mixing an organo-metallic salt of a transition metal with a low boiling solvent mixture and polymer solution, the polymer solution having an average viscosity selected at between about 110 cp to 180 cp, preferably 130 cp to 160 cp, providing the spinning tip at a location spaced from a support surface, electrospinning the resultant mixture from the spinning tip onto a support surface in an environment substantially isolated from external air currents.
