摘要

Polypyrrole/graphene nanocomposites have been synthesized via a simple in-situ pyrrolepolymerization process. The polypyrrole/graphene nanocomposites were analyzed by X-ray diffraction(XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) and Fourier transform infrared spectroscopy (FTIR) spectra. The resultsshow that the sphere-like polypyrrole particles with the size of less than 500 nm attach to the surface ofthe graphene nanosheet-shaped structures with the size of less than 10 μm. The polypyrrole/graphenenanocomposites modified glassy carbon electrode exhibits good electro-catalytic performance forformaldehyde in neutral solution. The nanocomposites modified glassy carbon electrode shows anirreversible current peak located at +0.2 V. The detection limit and linear detection range are 0.028 μMand 0.001–2 mM. The polypyrrole/graphene nanocomposites reveal great potential to detectformaldehyde in liquid environment.
