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...

Vilaithong © 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 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 NaBH 4 as a reducing agent. The XRD patterns of the product samples match well with the simulated PtCuNi alloy cubic structure and carbon phases. The SEM and TEM images show well-dispersed metal particles on the treated carbon supports. Metal particle sizes, measured from TEM micrographs, were 2.50-3.00 nm. The electrochemical performance of the PtCuNi alloy at the ratio of 6 : 1 : 1 on carbon Vulcan XC-72 delivered the highest current of 278.70 A/cm 2 • g pt at 600 mV. 2018-01-24T06:16:37Z 2018-01-24T06:16:37Z 2014-01-01 Journal 12299162 2-s2.0-84916203036 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84916203036&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/45730
