Abstract
A sonochemical procedure at room temperature for the preparation of gold (Au) nanoparticles loaded in mesoporous silica is described. It has been shown that the Au nanoparticles, with mean size of 3–4 nm in diameter and a fairly narrow size distribution, are dispersed uniformly within the pores of silica host.Keywords
