【摘要】 文中采用简单的一步溶剂热法合成了具有自组装花状结构的掺杂不同含量Ce的ZnO/NiO复合材料，并将其制备成传感器，研究了气敏性能。结果表明：当Ce的掺杂含量为2%时，复合材料表现出优异的三乙胺传感性能。该传感器在160℃的低工作温度下对三乙胺(TEA)具有较高的灵敏度，并具有优异的选择性和稳定性。对三乙胺的选择性高达56.87%,对其他气体选择性均小于10%。该传感器是一种很有前景的实用TEA探测器。更多还原

【Abstract】 In this paper, a simple one-step solvothermal method was used to synthesize self-assembled flower-like ZnO/NiO composites doped with different Ce contents and it was used to make sensors, and the gas sensitive properties were studied.The results show that when the Ce doping content is 2%,the composite exhibits excellent triethylamine sensing performance.The sensor has high sensitivity to triethylamine(TEA) at low operating temperature of 160 ℃ and has excellent selectivity and stability.The selectivity for triethylamine is as high as 56.87%,and less than 10% for other gases.The sensor is a promising practical TEA detector.更多还原
