Abstract
Nanometer sized particles containing titanium and platinum are prepared by a sonochemical process. Compounds of the metals are dissolved, suspended, or diluted in a low vapor pressure liquid medium, preferably at a sub-ambient temperature. A reducing gas is bubbled through the liquid as it is subjected to cavitation to affect the reductive decomposition of the metal compounds. Titanium and platinum are co-precipitated in very small particles.
