Abstract

The present study shows that nanoporous GeO_x supported Ag nanoparticle composite can be fabricated by one-pot dealloying of (Al_0.6Ge_0.3Mn_0.1)₉₈Ag₂ amorphous alloy. As-melt-spun (Al_0.6Ge_0.3Mn_0.1)₉₈Ag₂ precursor alloy consists of Ag₃Al nanoparticles embedded in the amorphous matrix. Immersion of precursor alloy in 5 wt% HCl solution leads to simultaneous dealloying of amorphous matrix and Ag₃Al nanoparticles. After dealloying process, Al and Mn atoms are almost completely dissolved out from the precursor alloy, forming a composite nanoporous structure consisting of Ag nanoparticles dispersed on nanoporous GeO_x.
