- Аннотация: Bi- and trimetallic platinum-ruthenium and platinum-ruthenium-tin catalysts with different atomic ratios of the metals in the surface layer were obtained by deposition of appropriate metal complexes onto highly dispersed carbon black and characterized by X-ray powder diffraction, energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Voltammetric measurements showed that the catalyst PtRu(3: 1)/C provides the highest current densities of methanol oxidation, in agreement with the structural data as well as with the electrochemical and power characteristics of the membrane electrode assemblies tested in single direct-methanol fuel cells.
