| Abstract: | Au@Pt core-shell nanoparticles with different scales were obtained by direct electrodeposition and proportion alteration of Au and Pt.The electrochemical behavior and electrocatalytic capability toward nitrite ion of Au@Pt-NPs glassy carbon modified electrode(Au@Pt-NPs/GC CME) which was made of different material proportion were studied.The results showed that the electrocatalytic activity was markedly enhanced for nitrite ion oxidation on the Au@Pt-NPs/GC CME,which was attributed to the cooperation between... |
