| titleOfInvention | Colloidal dispersions containing noble metal particles and acidic ionomer components and methods for their production and use |
| abstract | The present invention relates to a colloidal dispersion comprising nano-sized noble metal particles (eg, platinum or platinum alloy particles) and at least one ionomer component having an acidic group. The process for its production is based on a suitable noble metal precursor compound neutralization and dissolution process using a liquid acidic ionomer component followed by a reduction step. Suitable noble metal precursors consist of noble metal atoms, hydrogen atoms, oxygen atoms and optionally carbon atoms. Examples of precursors are H 2 Pt (OH) 6 , Pd (OH) 2 or Ir (OH) 4 and preferred reducing agents are aliphatic alcohols or hydrogen. The invention further relates to a precursor product for the production of such a colloidal dispersion, ie a composition comprising a noble metal precursor and at least one acidic ionomer compound. The colloidal noble metal dispersion is substantially free of contaminants such as salts or surfactants and may further contain a conductive or non-conductive support material. Colloidal noble metal dispersions can be used in the preparation of catalyst inks, ionomer layers, catalyst layers, electrodes or composite catalyst materials and have wide application in fuel cell technology (eg, PEMFC, DMFC or water electrolyzer). |
