Abstract
The nanocomposite of molybdenum disulfide (MoS2) and polyaniline (PANI) was prepared through in situ polymerization of aniline on the surface and interlayer of thin-layered MoS2. Owing to the physisorption of aromatic aniline onto the basal plane of MoS2, the electrochemical properties of MoS2/PANI nanocomposite were improved. And a novel electrochemical sensor based on MoS2/PANI nanocomposite was used to determine chloramphenicol by differential pulse voltammetry, exhibiting excellent performance. The detection range was from 1×10−7molL−1 to 1×10−4molL−1, with a high sensitivity and a low detection limit of 6.9×10−8molL−1. In addition, this sensor can be used for the determination of chloramphenicol in real samples.
