Time Dependent Morphological Evolution of Hydrothermally Derived MnO2 Nanostructures and Corresponding Methanol Vapor Sensing Performance

In this paper, different MnO2 nanostructures were grown employing hydrothermal route by varying the deposition time and corresponding alcohol vapor sensing performance were duly performed. Four types of hierarchical MnO2 nanostructures, viz. three-dimensional (3-D) nanoflowers (comprising of 2-D nanosheets), 3-D nanoflowers (comprising of a combination of 1-D nanorods and 2-D nanosheets), 3-D nano...
