Biosynthesized δ-Bi₂O₃ Nanoparticles from Crinum viviparum Flower Extract for Photocatalytic Dye Degradation and Molecular Docking.

ABSTRACT: Bioinspired delta-bismuth oxide nanoparticles (δ-Bi₂O₃ NPs) have been synthesized using a greener reducing agent and surfactant via co-precipitation method. The originality of this work is the use of Crinum viviparum flower extract for the first time for the fabrication of NPs, which were further calcined at 800 °C to obtain δ-Bi₂O₃ NPs. Physicochemical studies such as FTIR spectroscopy and XPS confirmed the formation of Bi₂O₃ NPs, whereas XRD and Raman verified the formation of the cubic delta (δ) phase of Bi₂O₃ NPs. However, HRTEM revealed the spherical shape with diameter 10-20 nm, while BET studies expose mesoporous nature with a surface area of 71 m²/gm. The band gap for δ-
