•The flower-sheet SnO2 sensor displayed particular response to the target gas.•Property improvement is independent of operating temperature and gas concentration.•Enhanced key gas sensing property meets basic needs for practical applications.•Sensing properties of nanocrystals can be improved by tailoring their shape and structure.
We successfully synthesized variant hierarchical assembled flower-like SnO2 via a simple hydrothermal technique and subsequent calcination. The structures and morphologies of the 3D nanostructures were investigated by means of powder X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM). The formation mechanism of these materials were proposed in detail. The gas-sensing performances of the as-prepared SnO2 were investigated towards ethanol. It is noted that the flower-sheet SnO2 sensor displayed particular response to the target gas, rendering SnO2 as a potential gas-sensing material for a broad range of future sensor applications.
