Abstract Iron oxide nanoparticles (Fe2O3 NPs) were fabricated through green route using pomegranate (Punica granatum) seeds extract. The Fe2O3 NPs were characterized by UV–vis, XRD, EDX, SEM and AFM techniques. The adopted green rout furnished semi spherical Fe2O3 NPs, uniformly distributed and particle size in the range of 25–55 nm. The LCMS/MS was performed for the identification of biomolecule present in the extract of pomegranate seeds and p-hydroxy benzoic acid, gallic acid, methyl gallate, catechin, kaempferol-3-O-sophoroside, 3-deoxyflavonoids, magnolol, ferulic acid, vanillic acid and pinocembrin along with other minor constituents were detected in the extracts using for Fe2O3 NPs. The synthesized Fe2O3 NPs showed excellent photocatalytic activity against reactive blue under UV light irradiation and maximum degradation of 95.08% was achieved with 56 min of reaction time. In view of promising activity, the Fe2O3 NPs could be used photocatalyst for the degradation of dyes in wastewater and pomegranate seeds extract can be applied as eco-benign and cost effective approach for Fe2O3 NPs synthesis.
