The influence of electrochemical annealing in CO saturated solution on the catalytic activity of Pt nanoparticles

Combining nondestructive, identical location-TEM (IL-TEM) with rotating disk electrode (RDE) measurements, the influence of different treatment procedures on the catalytic activity of C supported Pt nanoparticles is probed. IL-TEM shows that the treatment of the catalyst has only minor influence on its structure or the particle shape and size; in particular no treatment induced particle agglomeration is obsd. At the same time, both CO stripping and CO bulk measurements are significantly influenced by the electrochem. treatment. In consistence with previous studies this can be explained by the removal of defects in the CO adlayer structure while cycling in CO satd. soln. In contrast, however, CO annealing has no impact on the oxygen redn. reaction in the mixed kinetic-diffusion control potential region. [on SciFinder(R)]     «
