The catalytic activity and CO tolerance of the carbon-supported PdAu nanoparticles with a high dispersion and various surface compositions prepared by two different synthetic strategies were studied in hydrogen electrooxidation reaction (HOR). The PdAu/C catalysts with controlled surface composition of the bimetallic sites prepared by selective electrodeposition of Pd on preimmobilized Au particles (a model approach) proved to be a valid and convenient tool for determination of the surface composition of PdAu nanoparticles providing the maximum catalyst activity in HOR and CO tolerance. The PdAu/C catalysts prepared by impregnation of the Au/C substrate with Pd(II) nitrate solution followed heat treatments for obtaining the proper Pd-Au alloying (a pragmatic approach) showed the significantly higher HOR current densities compared to Pd-electroplated Au catalysts with similar surface Pd:Au composition. The catalysts containing the alloy Pd-Au particles of optimal surface composition are promising for application at the anodes of polymer-electrolyte membrane fuel cells
