In this work, we report a novel Au-Pt bimetallic nanoparticles (Au-PtNPs) decorated on the surface of nitrogen-doped graphene (NG) functionalized with 1,3,6,8-pyrenetetrasulfonic acid sodium salt (PyTS) by direct electrodeposition method. The results of SEM, energy dispersive X-ray spectroscopy (EDS) and electrochem. impedance spectrum (EIS) reveal that the Au-PtNPs were successfully anchored on the surface of NG sheets with a diameter of 20-40 nm. Further, the prepared Au-PtNPs/PyTS-NG nanocomposite exhibits superior catalytic activity for the oxidation of nitrite. Under optimal exptl. conditions, an amperometric sensor with a linear range of 0.5-1621 μM and a detection limit of 0.19 μM (S/N=3) for the detection of nitrite was set up and applied to real samples.
Talanta published new progress about Amperometric sensors. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Product Details of C19H34O2.
