Facile synthesis of reduced graphene oxide supported Pt-Pd nanocubes with enhanced electrocatalytic activity for chloramphenicol determination
In this work,we successfully prepared well-defined bimetallic alloyed Pt-Pd nanocubes (NCs) supported on reduced graphene oxide nanosheets (rGO-Pt-Pd NCs).Pt-Pd NCs were uniformly dispersed on rGO by hydrothermal treatment of preformed Pt-Pd NCs and GO in alkaline media.The detailed morphology,crystal structure and composition were well characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS).Furthermore,with the special structure of Pt-Pd NCs and the synergetic effects of Pt,Pd and rGO,the rGO-Pt-Pd NCs modified electrode exhibited excellent electrocatalytic performance in the sensing of chloramphenicol (CAP).The linear covered the range of 0.2-30 μM and the detection limit reached 0.1 μM(S/N=3).The modified electrode also displayed good stability,high reproducibility and satisfactory selectivity.
