COLLOIDAL CATALYST, AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a colloidal catalyst comprising catalytically active metal nanoparticles, some areas of which are covered with a layer containing a ligand-stabilized metal compound. The invention also relates to a method for producing colloidal nanocatalysts according to the invention. In said method, a ligand-stabilized complex of an ion of the catalytically active metal of the nanocatalyst is subjected to a thermal treatment at 180-250°C for 1 to 10 minutes in a hydrogen atmosphere along with the ligand-stabilized metal compound, the complex being soluble in an inert non-aqueous solvent.
