摘要：
Small platinum-particles have been synthesized in the form of spheres, chains, and composites by the chemical reduction of chloroplatinic acid. The morphology and size of the platinum particles depends on the nature of the reducing agent, presence and type of a protective agent as well as the reaction conditions. Polyvinylpyrrolidone was found to be the optimum protective agent due to its low protective ratio and high purity. The potential of this chemical-reduction approach is outlined. Investigations of the chemical and physical properties of these materials are encouraged.
