| 摘 要： | 以无机盐ZnSO4·7H2O和Na2S·9H2O为原料,用室温固相化学反应合成了ZnS;用XRD、TEM对产物的组成、大小、形貌进行了表征;用TG-DTA确定了ZnS的稳定温区.结果表明,产物为纳米颗粒,平均粒径为15nm左右,且610℃以下能在空气中稳定存在.另外还采用静态配气法测定了材料的气敏性能,发现ZnS对H2S有很高的灵敏度,且抗干扰能力强,有很好的应用前景.

| Abstract: | Nanometer ZnS powders were synthesized by the solid state reaction of ZnSO4·7H2O with Na2S·9H2O at room temperature. The gas sensitivity of ZnS obtained was discussed XRD and TEM show that the solid-state reaction at room temperature is feasible and reasonable and the mean grain size of ZnS crystalline is about 15nm. The translation temperature from ZnS to ZnO measured by TG-DTA is 610℃. The sensor based on ZnS obtained shows a good sensitivity and selectivity to H2S. |
