Abstract

The corrosion behavior of nanosized catalysts, in particular, of the commercial platinum catalyst and of PtCo synthesized on a XC72 carbon black carrier, are compared. Using electrochemical and structural research methods, it is shown that, under comparable conditions of the corrosion treatment, the PtCo/C system is less liable to degradation caused by the dissolution or aggregation of the catalyst particles.
