US09341590B2 Composite metal oxide materials including polycrystalline nanofibers, microparticles, and nanoparticles, gas sensors using the same as a sensing material thereof, and manufacturing methods thereof 有权
包括多晶纳米纤维，微粒和纳米颗粒的复合金属氧化物材料，使用其与其感测材料相同的气体传感器及其制造方法

Composite metal oxide materials including polycrystalline nanofibers, microparticles, and nanoparticles, gas sensors using the same as a sensing material thereof, and manufacturing methods thereof
Abstract:
Provided are a composite metal oxide material, a method of manufacturing the same, and a gas sensor using the same as a sensing material thereof. The composite metal oxide material may include polycrystalline nanofibers and at least one of microparticles and nanoparticles. The use of the composite metal oxide material makes it possible to improve structural, mechanical, thermal, and lifetime stabilities of the gas sensor. Further, the presence of the microparticles and/or nanoparticles allows the gas sensor to have a base resistance lower than that of a nanofiber-based gas sensor. Since the microparticles and/or nanoparticles are attached to the nanofibers, the composite metal oxide material can have an increased mobility of electrons or holes and an increased surface area, and thus, the gas sensor can have fast response/recovery speeds and high gas sensitivity.
Abstract(Chinese):

提供复合金属氧化物材料，其制造方法和使用该金属氧化物材料的气体传感器。 复合金属氧化物材料可以包括多晶纳米纤维和微粒和纳米颗粒中的至少一种。 使用复合金属氧化物材料可以提高气体传感器的结构，机械，热和寿命稳定性。 此外，微粒和/或纳米颗粒的存在允许气体传感器具有比基于纳米纤维的气体传感器低的基本电阻。 由于微粒和/或纳米颗粒附着在纳米纤维上，所以复合金属氧化物材料可以具有增加的电子或空穴的迁移率和增加的表面积，因此，气体传感器可以具有快速响应/恢复速度和高气体灵敏度 。
