Enhancement of catalytic activity of platinum-based nanoparticles towards electrooxidation of ethanol through interfacial modification with heteropolymolybdates

Autor: Krzysztof Miecznikowski, Artur Zurowski, Pawel J. Kulesza, Adam Lewera, Piotr J. Barczuk

Publikováno v: Journal of Power Sources. 195:2507-2513

As evidenced from the increase of electrocatalytic currents measured under voltammetric and chronoamperometric conditions, the activity of bimetallic Pt–Ru and Pt–Sn nanoparticles towards oxidation of ethanol is increased by modification of their
