英文摘要: This paper describes the synthesis of nanoporous AuPt nanoparticles (np-AuPt NPs) by galvanic replacement reactions that involve large-sized silver nanoparticles (Ag NPs) electrodeposited upon an indium tin oxide (ITO) film glass as a sacrificial template. Compared to a previous synthetic route based on the formation and dealloying of Ag/Au alloy nanoparticles, this method can easily fabricate nanoporous Au nanoparticles (np-Au NPs), as well as nanoporous AuPt nanoparticles. Structural characterization indicated that the products had a particle size of ∼170 nm with a ligament size of tens of nanometers. The fabricated np-Au NPs/ITO and np-AuPt NPs/ITO electrode were also tested and compared for the oxidation of hydrogen peroxide in a phosphate buffer solution (pH 7.0). The np-AuPt NPs/ITO...
