Solution route synthesis of PtCuNi nano-particles supported on treated carbon, electrocatalysts for ORR

© 2014, Hanyang University. All rights reserved. Pt-based ternary compounds supported on carbon have been proposed as a catalyst for oxygen reduction reaction (ORR), with relatively low over-potential, leading to high reaction rates compared to Pt/C catalysts. In this research, samples of 20% wt pla...

In this research, samples of 20% wt platinum-copper-nickel (at 2 : 1 : 1 and 6 : 1 : 1 ratios) supported on treated carbon (N115 and Vulcan XC-72) were prepared by solution route method, using NaBH4as a reducing agent.
