摘要：
Ring-shaped Ag-Pt nanoparticles (NRs) showing an LSPR peak were prepared via galvanic replacement of Ag nanoplates with H2PtCl6. The intensity and wavelength of the peak was controllable by changing the chemical composition of the NRs. The Ag-Pt NRs exhibited an electrocatalytic activity for oxygen reduction reaction, which was enhanced by the photoexcitation of LSPR.
