摘要：

Various palladium-carbon composites have been manufactured by autoclaving at 170 degrees C to be used as precursors for manufacturing bimetallic particles. The morphology of the manufactured items was comprehensively studied by scanning electron microscopy; the ultrafine metal palladium was found to have particles sizes lying in the range 30-120 nm. The specifics of hydrothermal reduction of gold(III) chloro complexes by palladium-carbon composites at 110 degrees C have been studied. An appreciable increase in gold(III) reduction rate was observed with the use of a palladium-carbon composite relative to the rate observed for ultrafine metallic palladium. Gold is reduced on a palladium-carbon composite to an individual metallic phase.
