Abstract: The scaling up of the intensity of beams of atomic clusters (nanoparticle beams) creates a new route to the fabrication of functional nanostructured materials. A challenge is to present, to the directed beam, high surface areas of the desired support material, for decoration by the clusters at local sub-monolayer densities. Then, the clusters and their properties can be preserved. Here we employ the Matrix Assembly Cluster Source (MACS) to demonstrate and characterise the deposition of lead clusters, with size of order 2 nm, into planar sheets of porous carbon paper, a material employed in electrode fabrication. We find that clusters are deposited to a depth comparable with the pore size of the carbon, ~ 50 μm, giving rise to a metal loading of ~ 0.05 mg cm−2 of carbon paper. The functionality of the nanocomposite film so created is demonstrated by its use as an electrode for the electrochemical generation of oxidising species suitable for water purification.

Funders: Swansea University. We thank Morris Mathews for his support of the cluster deposition with the MACS. We also acknowledge the support provided by the AIM Facility of Swansea University, which was funded in part by the EPSRC (EP/M028267/1), the European Regional Development Fund through the Welsh Government (80708) and the Welsh Government Sêr Cymru programme. We are grateful for the financial support of the work by Sêr Cymru II – WEFO ERDF Programme (80761) and the UK’s Global Challenges Research Fund via the Swansea University institutional grant and by EPSRC (Grant Reference No. EP/ K006061/2). A patent application (pending) based on part of the research work is in place.
