Controllable Tuning of the Performance of Volatile-Organic-Compound Sensing by MoS2 Using Au Nanoparticle Incorporation |
| 초록 |
Controlling the charge concentrations of 2D materials is a critical requirement for realizing versatility and potential application of these materials in electronics and sensors. In the present study, the gas-sensing performance of MoS2 has been significantly enhanced by controlled Au nanoparticle functionalization. MoS2 prepared by chemical exfoliation was decorated with nanoparticles and n-doping effect of Au nanoparticles was observed. This effect enables the tuning of the sensing of hydrocarbon-based volatile organic compounds (VOCs) and oxygen-functionalized compounds by MoS2. A significant step has been made with this study towards solving the limitations imposed by previous MoS2-based sensors, which mostly produce a single response to various VOC analytes. This controllable chemical doping process can eventually be used in early detection using multichannel sensing systems that have different responses and recognize patterns for target analytes. |
