溶胶-凝胶法制备In-Cd纳米复合氧化物及其气敏性能研究

摘要

Nanometer-scaled In2O3-CdIn2O4 and CdO-CdIn2O4 composite oxides were synthesized by sol-gel method.The morphology and structure of composites oxides were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD).The corresponding sensor exhibited good sensitivity and selectivity to ethanol and acetone vapor by changing the quantity of In2O3 and CdO in composite oxides.%采用溶胶凝胶法制备了In20rCdln2O4和CdO-Cdln2O4纳米复合氧化物,利用扫描电子显微镜(SEM)和X射线衍射仪(XRD)对复合材料的形貌和结构进行表征,并对其进行了乙醇、丙酮等多种气体的气敏性能测试.结果表明Cdln2O4材料复合h12O3和CdO后显著提高了对丙酮和乙醇气体的灵敏度和选择性.
