Novel methods preparing nanocrystalline SnO2 by electrodeposition to use overpotential |
| 초록 |
A novel process to prepare Sn/SnO2 nanocomposite and nanocrystalline SnO2 coating from nitrate solution by chronoamperometry and pulse technique, respectively, has been established in the present study. For the chronoamperometric technique, the percentage of Sn, ranging from 12.3 to 49.1 mol.% can be controlled by the applied voltage (-0.2 to -0.6 V). The co-deposited metallic Sn can be oxidized into nanocrystalline SnO2 at –0.1 V versus Ag/AgCl by using a pulse technique composed of alternatively a higher voltage stage (-0.2 to -0.6 V) and a low voltage stage (-0.1 V), and then a pure nanocrystalline SnO2 coating can thus be synthesized. The grain size of SnO2, ranging from 28.9 to 16.6 nm, could also be controlled by the applied voltage. |
