摘要：

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.
