• Supported nanoparticulate platinum is of great technological interest for applications including automobile emission control, hydrogenation reaction, and the electrocatalysts for polymer electrolyte membrane (PEM) fuel cells (PEMFCs) and electrolyzers, etc. (1−6) With increasing environmental concerns, clean power technologies, especially the PEMFC...
• Ammonium hexachloroplatinate ((NH4)2PtCl6), owing to its low thermal decomposition point, nonhygroscopic nature, and low solubility in aqueous solutions of NH4Cl, is an important intermediate compound in various platinum extraction/recycling processes. (8−10,25) In view of this, synthesis of Pt/C from the intermediate compound (NH4)2PtCl6 instead o...
• The present work aims to investigate the suitability of (NH4)2PtCl6 as the precursor for synthesis of the Pt/C electrocatalysts with 20 wt % Pt loading. A microwave-assisted polyol process, owing to its short processing times, is adopted for the synthesis of Pt/C from (NH4)2PtCl6 precursor. Impact of the process parameters, namely, reaction time an...
• Large-scale production of Pt/C from the (NH4)2PtCl6 precursor should be possible through various state-of-the-art routes for Pt/C synthesis. As synthesis of other Pt precursors such as H2PtCl6 requires additional processing steps such as thermal decomposition of (NH4)2PtCl6, the intermediate product, followed by dissolution of the Pt-sponge in conc...
