Construction of ZnCo 2 O 4 decorated ZnO heterostructure materials for sensing triethylamine with dramatically enhanced performance

In this paper, a sensor based on a novel ZnCo 2 O 4 /ZnO nanosheet-like p–n heterostructure was designed using a one-step hydrothermal method and utilized to dramatically improve the sensitivity toward triethylamine (TEA) gas.
