【摘要】：本文利用水热法制备氧化铜掺杂的碱式碳酸锌,并经过高温得到尺寸均匀的多孔氧化铜掺杂氧化锌纳米材料.用XRD、SEM等测试手段对材料的结构和形貌进行表征,并研究了掺杂前后多孔纳米材料对硫化氢的气敏性能.结果表明,氧化铜掺杂可以提升材料对硫化氢气体响应的灵敏度、选择性和稳定性,材料对H2S的最佳响应温度降低至180℃,对10 mg/L硫化氢的灵敏度可以达到60,对其他气体响应相对较弱,说明材料具有非常好的选择性.该氧化铜掺杂多孔氧化锌可适用于硫化氢气敏传感器.
[Abstract]:In this paper, copper oxide doped basic zinc carbonate was prepared by hydrothermal method, and porous copper oxide doped zinc oxide nanomaterials with uniform size were obtained by high temperature. The structure and morphology of the materials were characterized by XRD,SEM and the gas-sensing properties of porous nanomaterials before and after doping to hydrogen sulfide were studied. The results show that copper oxide doping can improve the sensitivity, selectivity and stability of the material to hydrogen sulfide gas. The optimum temperature of the material for H 2S is reduced to 180 鈩，
