Abstract
Carbon supported Pt–Cu and Pt–Co electrocatalystsElectrocatalysts
with increased platinum content on the surface layer of nanoparticles were synthesized by different chemical methods. The compositions, microstructures and electrochemical behaviors of these electrocatalysts were studied using the X-ray diffraction, thermogravimetry, X-ray fluorescence analysis, TEM and cyclic voltammetry. During stabilityStability
tests (1000 voltammetric cycles in HClO4 solution) the values of electrochemically active surface area (ESA)Electrochemically Active Surface Area (ESA)
for Pt–Cu/C catalysts reduced by 34%. Commercial Pt/C catalyst HiSPEC 3000 decreased ESAElectrochemically Active Surface Area (ESA)
value by 70% (from 102 to 30 m2g−1 (Pt)) in the similar tests. High stabilityStability

activity may be due to the fact that despite a comparatively large size of nanoparticlesNanoparticles (NPs)
