Abstract:
The rare earth metal oxide nanoparticles such as gadolinium oxide nanoparticles (Gd 2 O 3 NPs) have been synthesized by green synthesis process using methanolic extract of Moringa oleifera ( M oleifera ) peel. In this process, the Gd 2 O 3 NPs formation was observed at 280–300 nm in UV–Vis spectroscopy. The XRD pattern of the synthesized Gd 2 O 3 NPs was exactly matched with JCPDS No 3‐065‐3181which confirms the crystalline nature of Gd 2 O 3 NPs. In addition, Energy‐dispersive X‐ray spectroscopy (EDX) analysis was stated that Gd and O elements were present as 70.31 and 29.69%, respectively in Gd 2 O 3 NPs. The SEM and TEM analysis were said Gd 2 O 3 NPs are in rod shape and 26 ± 2 nm in size. Further the synthesized Gd 2 O 3 NPs were confirmed by X‐ray photoemission spectroscopy (XPS). The synthesized Gd 2 O 3 NPs were further examined for anti‐fungal activity against Alternaria saloni ( A saloni ) and Sclerrotium rolfsii ( S rolfsii ) and it showed moderate activity. Also, Gd 2 O 3 NPs evaluated as good antibacterial agent against different Gram +ve and Gram −ve bacteria. Moreover, the toxicity of the Gd 2 O 3 NPs on red blood cells (RBCs) of the human blood was determined using hemolytic assay, the obtained results were stated the synthesized Gd 2 O 3 NPs are nontoxic to the human erythrocytes. The photocatalytic activity against malachite green (MG) dye was tested and confirmed as 92% of dye was degraded within 2 hr by Gd 2 O 3 NPs. The results were stated the green synthesized Gd 2 O 3 NPs are good anti‐fungal agents, nontoxic and we can use as a photocatalyst. Copyright © 2019 John Wiley & Sons, Ltd.
