"Synthesis of novel hexagon SnO2 nanosheets in ethanol/water solution by hydrothermal process", Materials Letters, 2007, 61: 3705-3707
The novel hexagon SnO2 nanosheets are successfully synthesized
in ethanol/water solution by hydrothermal process. The samples
are characterized by X-ray diffraction (XRD), infrared ray
(IR) and transmission electron microscopy (TEM). By changing
the reaction conditions, the size and the morphology can be controlled.
Comparison experiments show that when the temperature increased
from 140 °C to 180 °C, the edge length of the hexagon nanoparticles
increases from 300–450 nm to 700–900 nm. On the other hand,
by adjusting the ratios of water to ethanol from 2 to 0.5,
SnO2 nanoparticles with different morphologies of triangle
and sphere are obtained. When the concentration of NaOH is
increased from 0.15 M to 0.30 M, a hollow ring structure can be obtained.
