This work studies the heat treatment effect of carbon-dispersed platinum and platinum-vanadium alloys on the kinetics of the oxygen reduction reaction (ORR) in acid medium. The catalyst powders were subjected to heat treatments at three temperatures for 1 h. The electronic and structural features of
The nanostructured platinum-bismuth catalysts supported on carbon (Pt 3 Bi/C, PtBi/C and PtBi 3 /C) were synthesised by reducing the aqueous metal ions using sodium borohydride (NaBH 4 ) in presence of a microemulsion. The amount of metal loading on carbon support was found to be 10 wt.-%. The catal
