摘要
The hydrolysis behaviour of some Mg-rich compounds (Mg(2)Ni, Mg(2)Cu, Mg(54)Ag(17) and Mg(3)Au) at room temperature has been systematically investigated. Ni, Cu, Ag and Au nanoparticles have successfully been prepared by the hydrolysis of these compounds. The Ni, Cu, Ag, and Au nanoparticles obtained by the hydrolysis method are close to spherical in shape with a particle size below 20 nm. A continuous skeleton of magnesium atoms could be the channel for the dissolution of Mg atoms in these Mg-rich compounds, which is helpful in the hydrolysis of these Mg-rich compounds. The hydrolysis of the Mg-rich compounds provides a new and relatively simple method for the production of transition metal nanoparticles.
