CTAB Enhanced Room-Temperature Detection of NO₂ Based on MoS₂-Reduced Graphene Oxide Nanohybrid.

ABSTRACT: A new NO₂ nanohybrid of a gas sensor (CTAB-MoS₂/rGO) was constructed for sensitive room-temperature detection of NO₂ by 3D molybdenum disulfide (MoS₂) and reduced graphene oxide (rGO), assisted with hexadecyl trimethyl ammonium bromide (CTAB). In comparison with MoS₂ and MoS₂/rGO, the BET and SEM characterization results depicted the three-dimensional structure of the CTAB-MoS₂/rGO nanohybrid, which possessed a larger specific surface area to provide more active reaction sites to boost its gas-sensing performance. Observations of the gas-sensing properties indicated that the CTAB-MoS₂/rGO sensor performed a high response of 45.5% for 17.5 ppm NO₂, a remarkable selectivity of NO₂, a
