Abstract

By using photocatalytically initiated electroless deposition (PIED) we have deposited macroporous metal films with highly ordered arrays of sub-μm (hemi)spherical pores directly onto the surface of insulating substrates for the first time. This has been achieved by sensitisation of the target substrate with a TiO2 photocatalyst followed by PIED of the target metal into the interstitial spaces of a template composed of hexagonally close packed polystyrene microspheres.
