specific Embodiment approach 1
[0019] Specific Embodiment 1: In this embodiment, the molar ratio of molybdenum atoms to carbon atoms in the gas-sensitive material based on graphene / molybdenum disulfide composite is 1:1-5, molybdenum disulfide is wrapped on the outer surface of graphene, and molybdenum disulfide The number of layers is 5-20, and the distance between each layer is 0.62-0.65nm.
specific Embodiment approach 2
[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the molar ratio of molybdenum atoms to carbon atoms in the gas-sensitive material based on graphene / molybdenum disulfide composite is 1:3. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0021] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the distance between each layer is 0.64 nm. Others are the same as those in the first or second embodiment.
