Visible light-responsive photocatalyst of SnO2/rGO prepared using Pometia pinnata leaf extract

The composite of tin oxide-reduced graphene oxide (SnO2/rGO) was prepared via a green synthesis of rGO using Pometia pinnata leaf extract followed by the dispersion of the SnO2 precursor. The composite was employed as a photocatalyst for the removal of methylene blue (MB) under UV and visible light....
