一种ZnCo2O4/ZnO异质结构复合气敏材料及制备方法
Abstract:
本发明公开了一种ZnCo2O4/ZnO异质结构复合气敏材料及制备方法，由片状氧化锌和钴酸锌复合而成，其中，所述氧化锌所占的质量百分比含量为4‑13.6%。本发明通过改变Zn(CH3COO)2•2H2O和Co(CH3COO)2·4H2O的添加合成了含有不同含量ZnO的ZnCo2O4/ZnO异质结构复合气敏材料。这意味着我们可以通过控制Zn和Co的摩尔比来合成不同掺杂比例的ZnO,制备的ZnCo2O4/ZnO异质结构复合气敏材料对三乙胺具有良好的敏感特性，在制造新型高效气体传感器方面具有广阔的应用前景。
Abstract(English):

The invention discloses a ZnCo2O4/ZnO heterostructure composite gas-sensitive material and a preparation method. The ZnCo2O4/ZnO heterostructure composite gas-sensitive material is formed by compounding flaky zinc oxide and zinc cobaltate, wherein the mass percent of the zinc oxide is 4-13.6%. Through change of the addition amounts of Zn(CH3COO)2.2H2O and Co(CH3COO)2.4H2O, the ZnCo2O4/ZnO heterostructure composite gas-sensitive materials with different ZnO contents are synthesized, which means that ZnO with different doping ratios can be synthesized by controlling the molar ratio of Zn to Co;the prepared ZnCo2O4/ZnO heterostructure composite gas-sensitive material has good sensitivity to triethylamine and has a wide application prospect in production of a novel efficient gas sensor.
