摘要：

Gold and silver particles prepared in Laponite suspensions by addition of reductant were studied. The particles obtained were characterized by ultraviolet-vis spectrophotometry and transmission electron microscopy. It was observed that the bimetallic gold/silver particles were alloy particles rather than core-shell particles. The Laponite does not operate as a hard template for the preparation of the particles. Instead Laponite acts a protective colloid to obtain nanometallic particles.
