Abstract
Amorphous silver nanoparticles of cn. 20 nm size have been prepared by the sonochemical reduction of an aqueous silver nitrate solution in an atmosphe re of argon-hydrogen. The silver nanoparticles have been characterized by T EM, X-ray diffraction, absorption spectroscopy, differential scanning calor imetry and EPR spectroscopy. The mechanism of the sonochemical reduction ha s been discussed, and occurs through the generation of hydrogen radicals du ring the sonication process.
