Figure 4From: Fabrication and NO2 gas sensing performance of TeO2-core/CuO-shell heterostructure nanorod sensorsResponses of the pristine TeO 2 nanorod and TeO 2 /CuO core-shell nanorod gas sensors. (a) Responses of the pristine TeO2 nanorod and TeO2/CuO core-shell nanorod gas sensors to NO2 as a function of the operation temperature. (b) Responses of the pristine TeO2 nanorod and TeO2/CuO core-shell nanorod gas sensors to different gases.Back to article page
