Al2O3掺杂ZnO微米花对丙酮超高灵敏度和优异选择性OA北大核心CSCDCSTPCD
Ultrahigh Sensitivity and Excellent Selectivity of Al2O3-doped ZnO Micro-flowers to Acetone
利用水热合成技术,成功制备具有孔道的纯ZnO微米花和Al2O3掺杂的ZnO(Al2O3-ZnO)微米花.通过X射线衍射(XRD)、扫描电镜(SEM)、电子能谱(EDS)对样品的形貌和结构进行表征.利用所得的纯ZnO和Al2O3-ZnO样品制备气敏元件,并对其气敏特性进行研究.结果表明:在工作温度为260℃时,基于Al2O3-ZnO的气敏元件对100×10-6的丙酮气体的灵敏度约为82.8,约为同条件下基于纯ZnO的气敏元件对丙酮气体灵敏度(18.…查看全部>>
Pore spaced pure ZnO and Al2O3-doped ZnO(Al2O3-ZnO) micro-flowers were successfully synthesized by hydrothermal method .The microstructure ,morphology and components were charac-terized by X-ray diffraction (XRD) ,scanning electron microscopy (SEM ) and energy-dispersive X-ray spectrometry (EDS) ,respectively .Gas sensors were made to investigate the gas sensing properties . The results reveal that the sensor based on Al2O3-ZnO shows a high sensitivity to ac…查看全部>>
