Autoclave Synthesis Pd-Au and Pd-Pt Nanoparticles on Carbon Substratess

Palladium-carbon composite material was synthesized by hydrothermal reduction of tetraammin palladium chloride (II) in alkaline media at 170 ° C. Morphology and size of the metal phase were investigated by scanning electron microscopy. Bimetallic particles Pd-Au and Pt-Pd on carbon substrates were prepared by interaction of palladium-carbon materials with muriatic solutions of gold(III) and platinum (IV) at 130 °C. It is found that varying contents of gold (III) and platinum (IV)in solution and the palladium metal in the initial composite may be prepared material with different ratios of metals.The phase of a palladium-gold is a substitutional solid solution was shown by X-ray diffraction.
