摘要：
Nanostructured Cu@Ptx/C catalysts with low platinum content (x = 0.8), comprising nanoparticles of core-shell architecture, were obtained by method of synthesis, which combines galvanic substitution of Cu at Pt and chemical reduction of Pt(IV). The obtained catalysts show high values of the electrochemically active surface area of platinum 80-100 m(2)/g (Pt) and higher both activity in the oxygen electroreduction reaction (ORR) and stability compared with commercial Pt/C catalyst HiSPEC 3000 (Johnson Matthey).
