Construction of SnO 2 /g-C 3 N 4 an effective nanocomposite for photocatalytic degradation of amoxicillin and pharmaceutical effluent

The current study mainly focused on the fabrication of 2D graphitic carbon nitride-supported tin oxide nanoparticles (SnO /g-C N ) for the effective degradation of Amoxicillin (AMX). Tin oxide (SnO ) NPs were prepared by green and easy modification technique, and then it is decorated over g-C N nanosheets. The structural morphology and surface composition of the synthesized SnO /g-C N nanocomposite were fully analysed by UV-Vis, XRD, XPS, and HR-SEM with EDAX, FT-IR, and BET analysis. The (HR-TEM) microscopy, the size of SnO NPs which as a diameter is about 6.2 nm. The Raman analysis revealed that the SnO /g-C N composite had a moderate graphitic structure, with a measured I /I value of 0.79. The degradation efficiency of antibiotic pollutant AMX and pharma effluent treatment was monitored by UV spectroscopy. The optical band gap of SnO (2.9 eV) and g-C N (2.8 eV) photocatalyst was measured by Tauc plots. To investigate the mechanism through the photodegradation efficiency of the catalyst was analysed by using different Scavenger EDTA-2Na holes (h ) has a greater contribution towards the degradation process. Under visible irradiation, SnO /g-C N nanocomposite has exhibited an excellent degradation performance of 92.1% against AMX and 90.8% for pharmaceutical effluent in 80 min.
