Abstract:
A sol includes metal oxide nanoparticles and stabilizer ions dispersed in an aqueous liquid. The nanoparticles include a metal selected from the group of platinum, palladium, rhodium, iridium, ruthenium and osmium and the molar ratio of metal: stabilizer ions is at least 0.7. A method of preparing supported catalyst materials includes contacting the sols with support materials.
