Azadirachta indica Leaf Mediated Synthesis of Iron Nanoparticles and Their Catalytic Application in Methylene Blue Degradation

Metal-free adsorption and photodegradation methods for methylene blue dye removal using different reduction grades of graphene oxide

“…The result reveals that the dye degradation is initiated by the demethylation of the molecules [ 41 ]. The identified m / z (mass-to-charge ratio) values at 301, 284, 271, 256, 242, 230, 218, 158, and 94 in comparison to the peak of MB dye at 284 [ 41 , 42 ] are indicative of potential fragments arising from MB degradation. Additionally, the photocatalytic reaction resulted in the production of intermediate compounds due to the disintegration of benzene rings.…”

“…Additionally, the photocatalytic reaction resulted in the production of intermediate compounds due to the disintegration of benzene rings. Finally, the breakdown of aromatic rings occurs and the resultant smaller intermediates subsequently undergo successive degradation reactions to yield carbon dioxide and water [ 41 , 42 ]. The possible photocatalytic degradation pathway of MB was determined through this study and shown in the supplementary file.…”
