Laser-assisted synthesis of Au-Ag alloy nanoparticles in solution

Article Abstract:

Au-Ag nanoalloys were prepared through three different procedures by using laser induced heating and it was found that the procedure, which uses 532nm laser irradiation, was advantageous for the production of spherical alloy nanoparticles. As the total concentration of Ag and Au in the mixture increased, large scale interlinked networks were observed revealing that this selective heating strategy can be extended to prepare other bi- or multi-metallic nanoalloys.

Preparation of colloidal nanoparticles of mixed metal oxides containing platinum, ruthenium, osmium and iridium and their use as electrocatalysts

Article Abstract:

The successful application of the synthetic material for the preparation of colloidal nanosized PtRuOsIrO in water is shown. Appropriate metal salts are hydrolyzed under basic conditions in the presence of the betain stabilizer C12H25(CH3)2N+(CH2)3SO3-, leading to nanoparticles in the size range of 1.2 to 1.6nm which are characterized by elemental analysis.
