Abstract

AgPt bimetallic hollow nanoparticles (AgPt-BHNPs) with an ultra-thin shell were synthesized. They show obvious localized surface plasmon resonance (LSPR) effects on electrocatalytic activity and CO poisoning tolerance in the methanol oxidation reaction (MOR) in alkaline media, which is attributed to the LSPR-induced localized photothermal effects and LSPR induced surface charge heterogeneity.
