一种新的低浓度气体（NO2，H-2和CO）的气敏平台包括均匀分布在多壁碳纳米管（CNT）表面的离散SnO 2纳米晶体。所得的混合纳米结构即使在室温下也是高度敏感的，因为它们的气体传感能力依赖于纳米晶体和CNT之间的电子转移。
A new gas-sensing platform for low-concentration gases (NO2, H-2, and CO) comprises discrete SnO2 nanocrystals uniformly distributed on the surface of multiwalled carbon nanotubes (CNTs). The resulting hybrid nanostructures are highly sensitive, even at room temperature, because their gas sensing abilities rely on electron transfer between the nanocrystals and the CNTs.
