Room Temperature Ammonia Sensing of MoS2 2D Sheets Decorated with Polyaniline (PANI)

In the present work, a selective room temperature (RT) operable ammonia (NH3) sensor based on molybdenum disulphide (MoS2) nanosheet decorated with polyaniline (PANI) (MoS2-PANI) is successfully developed. The material prepared by simple chemical in-situ polymerisation of aniline. Prior to gas sensing studies, morphological, thermal and compositional studies are carried out. These reveal good incorporation PANI into MoS2 nanosheets. property MoS2-PANI sensors studied compared bare PANI. shows opposite properties MoS2. However, nature followed in composite, but better stability. behaviour observed be excellent terms stability, selectivity, sensitivity, response recovery over pure sensor.
