Abstract: | Au‐Pt bimetallic nanoparticles film used as an efficient electrochemical sensor was prepared by self‐assembled Au‐Pt bimetallic nanoparticles on a glassy carbon (GC) substrate using thioglycolic acid as a linker. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) showed that the Au‐Pt nanoparticles self‐assembly film was dense and uniform. Electrochemical experiments revealed that Au‐Pt bimetallic nanoparticles film/GC electrode showed high electrocatalytic activity to the oxidation of nitric oxide. |
