Nanostructure сatalysts, сomposed of сomposites of platinum, ruthenium, polyelectrolytes and nanotubes

УДК 541.138


Electrocatalysts for methanol oxidation was studied. They were prepared on the base of carbon nanotubes, covered by polyelectrolytes with differently charged functional groups, which was changed by platinum with subsequent reduction. Then ruthenium was spontaneous deposited on metal platinum. The prepared catalysts were more active compared to commertial ETEK Pt-Ru (50:50 at. %) catalysts.

The Polymer Binders for the Electrodes of Lithium Batteries. Part 2. Synthetic and Natural Polymers

The second part of the review describes the prospects of using alternative polymer binders for composite electrodes of lithium electrochemical systems. Possible options having been taken into account, the most popular commercially-available synthetic polymers with functional group (the ones forming aqueous solutions or dispersions predominantly) and water-soluble polymers of natural origin are considered. The versatility of such materials is their distinctive feature.
