英文摘要: A novel Mo doped reduced graphene oxide/polyimide (Mo-rGO/PI) composite membrane sensor for dopamine (DA) has been successfully prepared by a simple and effective method. In this work, the rGO was doped into PI to prepare polymer composite membrane. Although rGO has a certain degree of catalytic activity for DA, more important is Mo doped rGO/PI film can enhance its electrocatalytic activity towards the oxidation of DA, and so far there is almost no report that MoO2 can catalyze DA. In order to find the best film, different doped ratios of Mo powder are further investigated, and the combined characterization by X-ray photoelectron spectra and energy-dispersive X-ray spectroscopy indicate that Mo exist in rGO/PI film in the form of MoO2. Under optimal conditions, the Mo doped rGO/PI film exhibits excellent catalytic activity to DA, with a linear response throughout the concentration range from 0.1 to 2000 mu M, it also shows long-term stability and good reproducibility, and performs well for detection of DA in human blood serums and injection. These results suggest that the novel Mo-rGO/PI film is a promising candidate for the accurate and reliable detection of DA signals in biological samples. (C) 2016 Elsevier B.V. All rights reserved.
