Synthesis and Investigation of Fe doped SnO2 Nanoparticles for Improved Photocatalytic Activity under Visible Light and Antibacterial performances

ABSTRACT Pristine and iron (Fe) doped tin oxide (SnO2) nanoparticles (NPs) were prepared by using a microwave aided co-precipitation method and the effect of doping on structural, optical and photocatalytic belongings have been investigated by XRD, FTIR, HR-SEM with EDX mapping, UV-Vis. DRS and Photoluminescence (PL) spectra respectively. XRD analysis has revealed a tetragonal SnO2 structure and the typical crystalline size was found to be between 28 nm and 17 nm. Photoluminescence spectra displayed a robust UV emission broadband peaking around 392.5 nm. The 4 % of Fe doped SnO2 NPs had higher photocatalytic action associated with the pristine and 2 % of Fe-SnO2, and maximum MO dye degradation efficiency of 87.2 % has been attained 200 min under visible light Moreover, the studies prove that antibacterial activities of produced Fe doped SnO2 NPs have a momentous performance against various gram-positive (G+) and gram-negative (G-) bacteria.
