Research Abstract

Nanoporous Pd and Ni were successfully fabricated by dealloying(selective dissolution from binary alloys). The diffusion of nobler metals at alloy/electrolyte interface plays an important role in the formation of nanoporous structure ; the difference in the standard electrode potential does not always allow the dissolution of less noble element(and subsequent nanoporosity evolution). Also, catalytic properties of synthesized nanoporous Pd and Ni were evaluated.
