摘要
In this paper, a sensitive novel non-enzymatic nitrite electrochemical sensor based on Pt nanoparticles loaded Ni (OH)(2)/Multi-Walled Carbon Nanotubes nanocomposites (Pt/Ni(OH)(2)/MWCNTs) was described. The composition and morphology of the Pt/Ni(OH)(2)/MWCNTs were characterized by transmission electron microscope and investigated energy dispersive X-ray spectra respectively. Results showed that the Pt nanoparticles could be anchored on the surface of the Ni(OH)(2)/MWCNTs uniformly through a simple reduction process. The electrochemical investigation of the sensor revealed that the Pt/Ni(OH)(2)/MWCNTs exhibited remarkable electrocatalytic performance toward nitrite oxidation, with a sensitivity of 145 mu A mM(-1) cm(-2) and a low detection limit of 0.13 mM. Moreover, the obtained Pt/Ni(OH)(2)/MWCNTs modified GCE with excellent reproducibility and selectivity also allows for practical application. It is expected that the combination of noble metal with Ni(OH)(2)/MWCNTs could be expanded to enhance the catalytic performances of nanocomposites and used for the construction of high-sensitive electrochemical sensors.
