Construction of SnO/g-CN 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-CN) 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-CN nanosheets. The structural morphology and surface composition of the synthesized SnO/g-CN 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-CN 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-CN (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-CN nanocomposite has exhibited an excellent degradation performance of 92.1% against AMX and 90.8% for pharmaceutical effluent in 80 min.
