Reduction of H2PtCl6 with three carboxylic acids (citric acid (CA), formic acid (FA), and ascorbic acid (AA)) and ethylene glycol at different pH values was studied. A kinetic analysis revealed that AA provides the fastest reduction of the platinum precursor (1300–1500 s), while the reaction medium redox potential corresponding to the nucleation onset of Pt NPs decreases in the order AA > FA > CA. The optimal range of pH values for the synthesis by the polyol method was determined. This allows one to obtain platinum NPs of the smallest size (2.3–2.5 nm) with the narrowest size distribution. The best-performing Pt/C catalyst we have synthesized exhibits a large electrochemically active surface area of about 79 m2 gPt−1 and an ORR mass activity of up to 434 A gPt−1 at 0.9 V, thus outperforming the commercially available catalyst HiSPEC 4000 (nearly twofold improvement) at identical platinum loading (about 40 wt.%).
