One pot aqueous synthesis of nanoporous Au85Pt15 material with surface bound Pt islands: an efficient methanol tolerant ORR catalystElectronic supplementary information (ESI) available: Materials, characterization, catalyst and MEA preparation, Fig. S1-S9. See DOI: 10.1039/c4nr04712e
For the first time, we are reporting the synthesis of Au 100− x Pt x nanoporous materials in the size range of 7-10 nm through the galvanic replacement of Ag by Pt from Au 100− x Ag 2 x spherical nano-alloys ( x = 20, 15, 10 and 5) in an aqueous medium. The galvanic replacement reaction follows the...
