英文摘要 | Bimetallic nanoparticles provide a new opportunity for enhancing electrocatalytic activity because of some possible synergetic effects. In this study, different compositions of Au-Cu bimetallic nanoparticles are prepared via a simple hydrothermal method. The structure of Au-Cu bimetallic nanoparticles is characterized by using X-ray absorption fine structure (XAFS) techniques, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The correlations between electrochemical performance and the compositions of Au-Cu bimetallic nanoparticles on the determination of arsenic(III) are investigated through square wave anodic stripping voltammetry (SWASV). It is found that the amount of copper (Cu) in Au-Cu bimetallic nanoparticles is critical to the detection of arsenic(III). The XAFS results indicated that the Au-Au bond length (RAu-Au) can be influenced by the Cu concentration in the materials. Different RAu-Au of Au-Cu nanoparticles lead to the different electrochemical catalytic activity toward arsenic(III), further revealing the different electrochemical behavior. Compared with Au nanoparticles and commercial Au electrode, the Au-Cu bimetallic nanoparticles showed enhanced electrochemical performance with high sensitivity at ppb level, low detection limit. Moreover, the Au89Cu11 bimetallic nanoparticles exhibited ultra-high anti-interference performance on the detection of arsenic(III). (C) 2016 Elsevier B.V. All rights reserved. |
