Paper Abstract

Efficient preparation of dispersions of platinum nanoparticles was achieved by reduction of chloroplatinate ions (PtCl62-) by hexadecylaniline (HDA) as the reaction occurred at the air/water interface where the insoluble monolayer of HDA was spread. The obtaining of the platinum nanoparticles, formed spontaneously at the air–water interface by HDA enables their facile transfer as multilayers onto suitable solid supports by means of the Langmuir-Blodgett technique. Langmuir-Blodgett films were characterized by Atomic force microscopy (AFM) imaging and X-ray photoemission spectroscopy (XPS).
