摘要：

The ultrasound irradiation of aqueous solutions of PtCl62- was found to produce colloidal platinum of about 3 nm in diameter. The presence of aliphatic alcohols significantly enhanced the reduction process. It is shown that the extent of reduction of PtCl62- in the presence of alcohol is directly related to the Gibbs surface excess of the alcohol at the air-water interface. The significance of this is discussed in relation to ultrasound induced cavitation in solution. (C) 2000 Elsevier Science B.V. All rights reserved.
