Abstract

An alternative solvent-free method is explored for the processing of Pt/C, Ni/C and Pt-Ni catalysts based on a low-pressure radio-frequency plasma treatment of solid (powder) precursors. A porous carbon xerogel is used as catalyst support, mixed with an organometallic precursor and treated in a plasma discharge at different power and in different plasma chemical environments. The nucleation of metal nanoparticles, their morphology evolution and chemical state are characterized by combining in-situ optical emission spectroscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Results show that the plasma processing offers a high flexibility in tuning the size and oxidation state of Ni and Pt nanoparticles and also allows for a controlled functionalization of the carbon support; these properties demonstrate the high potential of plasma processing route for the fabrication of green and efficient catalysts nanomaterials.
