Growth and gas sensing properties of self-assembled chain-like ZnO nanostructures

摘要

This work reports the preparation of self-assembled chain-like ZnO nanostructures and investigation of their gas sensing properties. Chain-like ZnO nanostructures of high density and homogeneity were obtained by electrochemical anodization method. The structures were prepared on alumina, silicon and flexible substrates. Optical properties of the structures were investigated. Gas sensing properties of obtained structures have been tested in a wide range of operating temperatures and towards different gases.
