“…7(ii), deposited over a 90 min period, an increase in the upper pore diameter to $900 nm is observed, this equates to a metal layer thickness of approximately 282 nm. Thus, as previously reported for the Ag system, 6 we also observe an increase in Pd lm thickness with increasing deposition period.…”

“…As described in our previous communication, the extent of the metal deposition, as measured by deposit thickness, is found to depend upon the deposition period. 6 During the initial 30 min, the metallisation process occurs largely through photocatalytic metal nucleation; 7,9 the Ag deposited in this time persists aer the removal of the microsphere template, conrming that deposition occurs directly onto the m-TiO 2 through photocatalytic means. Ag nucleation on the TiO 2 sensitised substrate occurs primarily around the point of contact between individual microspheres and the substrate surface, forming isolated rings of Ag with a diameter of <200 nm, Fig.…”

“…This suggests that the microsphere array acts to inhibit the metal deposition through: (i) restricting the access of the electroless plating constituents bath to the underlying m-TiO 2 layer; and/or (ii) attenuating the intensity of the UV irradiation reaching the TiO 2 , so reducing the photocatalytic effect and the number of nucleation sites formed. Despite these inhibiting effects, the deposition of nanoporous Ag lms through PIED is demonstrated and, as deposited metal lm thickness increases with deposition time, 6 the reduced rate of metal deposition can be easily compensated for with an increased immersion time in the Ag plating bath.…”

“…From a materials processing perspective, it would be convenient if an electroless deposition-based fabrication route existed whereby the porous metal could be formed directly onto the insulator surface. The rst report of such a route was made in our previous communication, 6 in which we developed a novel method to prepare porous metal lms with ordered arrays of sub-mm spherical voids on non-conducting substrates using our insulator metallisation process of Photocatalytically Initiated Electroless Deposition (PIED). [7][8][9] These lms are prepared by electrolessly depositing metal into the interstitial spaces of a hexagonally close packed polystyrene (PS) microsphere array.…”

We present the novel use of Photocatalytically Initiated Electroless Deposition (PIED) for the deposition of metal films with highly ordered arrays of sub-µm (hemi)spherical pores directly onto the surface of insulating organic membrane-based substrates. This is achieved by sensitisation of the target substrate with a TiO2 photocatalyst followed by the self-assembly of a hexagonally close packed polystyrene microsphere template at the substrate surface. Metallisation then occurs through PIED into the template interstices and directly onto the TiO2 sensitised membrane surface. The dimensions of the resultant pores in the deposited metal are determined by the size of the template microspheres while metal film thickness may be controlled by the deposition period. The fabrication of nanoporous metal by this novel method adds a conductive and permeable metallic structure of high surface area to an otherwise electrically insulating polymer membrane surface. Such metallised insulating membranes have potentially wide applications in membrane and separation technology, desalination and electrode / solid electrolyte composites for fuel cells.
