It is revealed that Pd(II) species are reduced on the GaAssurface and yield Pd nanoparticles during the process of Pd immobilization and the subsequent heat treatment. A comparison with the results on GaAs without S-termination suggests that the reduction of Pd is promoted by hydroxy groups during the Pd immobilization and by S during the heat treatment.}, title = {Sulfur-Mediated Palladium Catalyst Immobilized on a GaAs Surface}, volume = {111}, year = {2012} }
