• We demonstrate that Pt/PSi composite powders can be prepared by a simple method involving the metal-assisted electroless chemical etching of Si powders. In X-ray photoelectron spectroscopy and optical measurements, Pt layers are deposited on a Si surface together with the formation of a porous structure. It is found that the oxidation state of Pt layers strongly depends on the conditions for the preparation of Pt/PSi composite powders. Furthermore, Pt/PSi composite powders show an enhanced catalytic activity caused by the Pt metal layer deposited on the nanostructured Pt/PSi surface.
