Abstract:
Improved oxygen reduction reaction catalysts include octahedral nanoparticles of a platinum-copper-nickel alloy contacted by a secondary ionomer. The alloy can have a formula of Pt2CuNi, and the secondary ionomer can include an ionic liquid, 1-methyl-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidin-9-ium 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate ([MTBD][C4F9SO3]). The oxygen reductions catalysts have improved stability, as well as mass area and specific area comparted to competing catalysts.
