Here we design and fabricate the molybdenum disulfide (MoS₂)/graphene based hybrid sensor and evaluated the gas sensing performance of numerous kind of gases (Ethanol, methanol, acetone, CO, NO₂ and formaldehyde) using clad removed fiber optic method. The hybrid sensors were characterized by XRD, SEM, TEM, EDS, Raman and BET analysis. The interconnect of MoS2 spherical nanoparticles with 2D graphene sheet offer large active surface area, which facilitate the more absorption properties of gas molecules with presence evanescent wave light. The hybrids sensor showed outstanding sensitivity (61%), rapid response (22 s) and recovery time (35%) towards NO₂ gas than bare MoS₂ sensor. The enhanced gas sensing properties is due to the synergistic effect of MoS₂ and 2DG. Thus, the proposed field sensor would be gorgeous due to its low cost production, effortlessness and accuracy. It would be a prospective application on high performance gas sensor device. The gas sensing mechanism of the proposed sensor is discussed in briefly.

在这里，我们设计和制造了基于二硫化钼（MoS ₂）/石墨烯的混合传感器，并使用包覆去除光纤法评估了多种气体（乙醇，甲醇，丙酮，CO，NO ₂和甲醛）的气体传感性能。通过XRD，SEM，TEM，EDS，拉曼和BET分析对混合传感器进行了表征。MoS2球形纳米颗粒与2D石墨烯片的互连提供了较大的有效表面积，这有助于在存在e逝波光的情况下提高气体分子的吸收性能。混合传感器比裸MoS ₂表现出出色的灵敏度（61％），快速响应（22 s）和对NO ₂气体的恢复时间（35％）传感器。增强的气体传感性能归因于MoS ₂和2DG的协同作用。因此，提出的场传感器由于其低成本的生产，不费力和准确性而将是华丽的。它将在高性能气体传感器设备上有前瞻性的应用。简要讨论了所提出的传感器的气体传感机制。
