A facile one-step hydrothermal synthesis of a novel NiO/ZnO nanorod composite and its enhanced ethanol sensing property

摘要

In this study, a novel high length-diameter ratio NiO nanorods decorated with uniform ZnO nanoparticles was synthesized via a facile one-step hydrothermal process. It was a surprise to find that the NiO/ZnO nanorods heterostructure based sensor demonstrated much more excellent ethanol gas sensing properties than that of undoped NiO nanorods. This enhancement of sensing properties may be attributed to their synergetic effect as well as the heterojunction at interface between the NiO nanorods and ZnO nanoparticles. (C) 2019 Elsevier B.V.
