摘　　要：以硝酸铜为铜源,六亚甲基四胺为碱源,采用水浴加热法合成牡丹花状亚微米级氧化铜颗粒;采用扫描电镜对产物的组成和形貌进行表征;通过静态配气法对产物气敏性能进行研究。结果表明:所得氧化铜颗粒由三角片状微结构组成,随着六亚甲基四胺用量的增加,其形貌经历了纺锤状—蝴蝶状—牡丹状的递变;花状氧化铜颗粒对硫化氢气体具有较高的灵敏度。Peony-like submicrometer cupric oxide particles were synthesized by the water bath heating method using copper nitrate as copper source and methenamine as alkali source. The size and morphology of the as-prepared products were characterized by scanning electron microscopy. The gas sensing property of the product were measured by the stationary state gas distribution method. The results indicate that the cupric oxide particles are composed of microstructured triangular nanosheets. The morphology of the cupric oxide particles alters from spindle-like, viabutterfly-like, to peony-like microstructure as the concentration of methenamine increases. The cupric oxide particles have better response to hydrogen sulfide.
