Progress in ZnO Nanostructure for Sensing Based Using Low Temperature Method

Semiconductor ZnO nanostructure with low dimension for gas sensing has been studied due to its features such as good sensitivity, selectivity and show fast response in gas sensing detection. This attractive material could be growth in a variety nanostructure such as one-dimensional nanostructure eg; the nanorods, nanowire, nanobelts and nanotubes and two-dimensional (2D) eg; nanosheet, nanodisk and nanoflakes. ZnO can also be tuned to perform a mixture of nanostructure to improve the performance of its detection. This paper provides the report in synthesis of ZnO nanostructure with a simple method at low temperature for sensor application.
