چکیده مقاله :

Nanocrystalline boron doped tin oxide and boron and silver co-doped SnO2 was successfully prepared by using simple sol-gel method. The structural property of as-prepared nanocrystalline materials was investigated by using X-ray powder diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy. The infrared spectra of the prepared samples showed an incorporation of B and Ag in the SnO2 nanocrystals. The X-ray powder diffraction pattern of the as prepared sample demonstrated the formation of a rutile structure of SnO2 nanocrystallites with particle size of 35 nm and 98 nm for boron doped and co-doped samples respectively. The two different Sn-O bond distances are found to be varying in a different manner for the doped samples unlike pristine samples. A significant lattice microstrain was observed for co-doped samples indicating local lattice distortion. The prepared samples showed significant anti-microbial activities against some Gram-Positive & Gram-Negative bacteria in both water and DMSO medium. The prepared materials can be effective for water remediation.
