Curcumin stabilized Bi2S3@Ce2S3 nanoflowers: An efficient photocatalyst against harmful bacteria and toxic cationic dyes in aqueous medium

Year: 2025

Type: article

Abstract: Designing nanomaterials with controlled sizes is crucial for effective water pollution remediation. In this study, curcumin-stabilized CBi 2 S 3 @Ce 2 S 3 NFs nanoflowers (NFs) were synthesized via an ultrasonication-assisted hydrothermal method using Bi 2 S 3 NPs, and Ce 2 S 3 nanoflakes. Structural and compositional analyses were performed using SEM, TEM, XRD, EDX, IR, XPS, and TGA, confirming the formation and stabilization of NFs. The photocatalytic activity of the NFs was assessed through the degradation of Methylene Blue (MB), Malachite Green (MG), and Rhodamine B (RhB), showing respective efficiencies of 90 %, 88 %, and 44 % in 120 minutes. In a ternary dye mixture, the degradation efficiencies were found 64.1 % (MB), 63.4 % (MG), and 28.1 % (RhB). The NFs also demonstrated antimicrobial activity against various bacterial strains and Candida albicans. Phytotoxicity studies on green gram sprouts revealed the NFs were non-toxic up to 15 mg/20 mL over 22 days.
