摘要：

Bimetallic PtcoreAgshell nanoparticles demonstrate the ability to catalyze methylviologene reduction with hydrogen in water-alkali solutions, which is inherent in platinum nanoparticles. The onset of the reaction is preceded by an induction period whose duration increases with the thickness of a silver layer covering a platinum core. The reaction slows down with a rise in the thickness of the silver layer. The mechanism of catalysis is discussed.
