The present study shows that nanoporous GeOx supported Ag nanoparticle composite can be fabricated by one-pot dealloying of (Al0.6Ge0.3Mn0.1)98Ag2 amorphous alloy. As-melt-spun (Al0.6Ge0.3Mn0.1)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 GeOx.
