Chemistry and Pharmacology
Abstract Preprepared nanometals stabilized by surfactants may be used as precursors for a new type of heterogeneous catalyst. Independent of the support these mono– or plurimetallic precursors may be optimized dependent on the size, composition, and structure of the particles. Further, the active metal surface may be shielded against poisons by the protective shell. In addition, doping agents may be used in order to enhance the catalytic performance. The cis–selective partial hydrogenation of 3–hexyn–1–ol giving leaf alcohol, a valuable fragrance, and the selective oxidation of glucose giving sodium gluconate are current examples for the application of supported nanometal colloids in fine chemicals catalysis.
