Abstracts:This paper demonstrates the synthesis of SnO2 nanoparticles using a simple hydrothermal route in the presence of the surfactant hydrazine at 100oC for 12 h. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) were employed to characterize the as-prepared product and optical property was studied by UV–vis diffuse reflectance spectroscopy (DRS). The X-ray diffraction (XRD) pattern of the as-prepared sample is indexed to the tetragonal structure of SnO2 and the calculated particle size is 22.4 nm, which is further confirmed by TEM. The selected area electron diffraction (SAED) patterns showed continuous ring patterns without any additional diffraction spots and rings of secondary phases revealing their crystalline structure. Analysis of the DRS spectrum showed the band gap of the synthesized SnO2 to be 3.6 eV. The anionic surfactant hydrazine plays a key role in the formation of the SnO2 nanostructures. A probable reaction for the formation of SnO2 nanoparticles is proposed.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
