Abstract

Reducing the size of bulk metals to nanometer scale can result in the display of extraordinary physical and chemical properties. Typically, metal nanoparticles (MNPs) are prepared from metal atoms or metal salts and show remarkable catalytic properties. Metal nanopores (MNPores) are prepared through a totally reverse approach (from bulk metal to nanosized metal): alloy M1M2 is fabricated from metal M1 and metal M2, and then dealloying of M2 results in a nanoporous framework of metal M1. This account summarizes MNPore-catalyzed reactions developed in our group, and their comparison with other representative catalytic reactions.
