Low-temperature vapor–solid growth and excellent field emission performance of highly oriented SnO2 nanorod arrays

Comparative gas sensor response of SnO2, SnO and Sn3O4 nanobelts to NO2 and potential interferents

“…Furthermore, the surfaces of the nanobelts are flat and smooth [24,26], though the Sn 3 O 4 belts present a layered surface [18]. The presence (or not) of metallic spheres at one extremity of the nanobelts is related to their growth mechanisms, which occurs by a self-catalytic vapor-liquid-solid (VLS) process [24,26,30] for SnO nanobelts (the Sn peak at XRD is related to the catalytic metal) and by vapor-solid (VS) process [31,32] for both SnO 2 and Sn 3 O 4 nanobelts. Moreover, these belts were also characterized by XRD and TEM [18,24,31] showing that they are single crystalline and SnO 2 nanobelts grow in the (1 0 1) plane of tetragonal structure, SnO nanobelts grow in the [1 1 0] direction of orthorhombic structure, and Sn 3 O 4 nanobelts growth is related to the (1 0 1) plane of triclinic structure.…”

Enhancement of Field Emission and Photoluminescence Properties of Graphene-SnO2 Composite Nanostructures

“…However, detailed studies on the effect of graphene buffer layers on field-emission properties of SnO 2 have not yet been performed. For these reasons, it is expected that the SnO 2 composite nanostructures with graphene buffer layer would increase the electron-transport capability, and improve field-emission properties.…”

The Effect of Eu Doping on Microstructure, Morphology and Methanal-Sensing Performance of Highly Ordered SnO2 Nanorods Array

“…It could bring many surprising discoveries for us. Recently, a few prepared technologies of SnO 2 nanoarrays, such as the hydrothermal method [23], thermal evaporation approach [24], chemical vapor deposition technology (CVD) [25], and so on, have already been reported. However, these strategies are performed on rigorous equipments, and multiple steps, which limits their application.…”
