Design of highly sensitive volatile organic compound sensors by controlling NiO loading on ZnO nanowire networks

Abstract

Highly sensitive detection of volatile organic compounds, such as C2H5OH and HCHO, has been achieved by decorating p-type NiO nanoparticles on n-type ZnO nanowire networks, whereas the incorporation of Ni into the lattice of the ZnO nanowires deteriorated the gas sensing characteristics.
