Preparation and characterization of different metal oxide (NiO, WO, ZnO, SnO and NbO) nanostructures for chemical sensing are presented. p-Type (NiO) and n-type (WO, SnO, ZnO and NbO) metal oxide nanostructures were grown on alumina substrates using evaporation-condensation, thermal oxidation and hydrothermal techniques. Surface morphologies and crystal structures were investigated through scanning electron microscopy and Raman spectroscopy. Furthermore, different batches of sensors have been prepared, and their sensing performances towards carbon monoxide and nitrogen dioxide have been explored. Moreover, metal oxide nanowires have been integrated into an electronic nose and successfully applied to discriminate between drinking and contaminated water.
介绍了用于化学传感的不同金属氧化物（NiO、WO、ZnO、SnO和NbO）纳米结构的制备与表征。采用蒸发冷凝、热氧化和水热技术在氧化铝衬底上生长了p型（NiO）和n型（WO、SnO、ZnO和NbO）金属氧化物纳米结构。通过扫描电子显微镜和拉曼光谱研究了表面形貌和晶体结构。此外，制备了不同批次的传感器，并研究了它们对一氧化碳和二氧化氮的传感性能。此外，金属氧化物纳米线已被集成到电子鼻中，并成功应用于区分饮用水和受污染水。
