Abstract
The green synthesis method of SnO2 nanocrystals have been developed in recent year in view of their potential application as photoelectrode in dye-sensitized solar cells (DSSCs). The effect of the size and morphology of SnO2 nanocrystals on efficiency of DSSCs have been reported. In order to prepare SnO2 nanocrystals with different size and morphology, several synthesis methods have been developed. In this report, the facile green synthesis of SnO2 nanocrystals by hydrothermal method at relatively low temperature using plant extracts in acid and base solution have been carried out. SnO2 nanocrystals as synthesized were characterized by an X-Ray Diffractometer (XRD) and a Scanning Electron Microscope (SEM). The results showed that the all products were phase SnO2 nanocrystals which obviously showed by the XRD pattern. Furthermore, SEM images analysis clearly showed the morphology different of SnO2 nanocrystals synthesized with and without the addition of plant extracts. These results indicated that the properties of SnO2 nanocrystals could be controlled using plant extracts in the solution reaction.
