CdO nanoflake arrays on ZnO nanorod arrays for efficient detection of diethyl ether†
Abstract
We report the template synthesis and gas detection of CdO porous nanoflake arrays (P-NFAs) on ZnO nanorod arrays. The P-NFAs possesses a large surface-to-volume ratio, high-energy exposed surface, unimpeded channels for gas flow, and hierarchical holes. As a result, the device exhibits excellent sensing properties upon exposure to diethyl ether.
