ملخص

The nature of H-atoms adsorbed on M0-nanoparticles is of major importance in many catalyzed reduction processes.Using isotope labeling,wedetermined that hydrogen evolution from transient {(M0-NP)-Hn}n proceeds mainly via the Heyrovsky mechanism when nislarge (i.e., the hydrogens behave as hydrides) but mainly via the Tafel mechanism when nissmall (i.e., the hydrogens behave as atoms). Additionally, the relative contributions of the two mechanisms differ considerably for M = Au and Ag. The results are analogous to those recently reported for the M0-NP-catalyzed de-halogenation processes.
