Photocatalytic Degradation of Textile Dye Using Green Synthesized Nanoparticles

Abstract

In recent years, plants have been used as reducing agents for the synthesis of nanoparticles in a short time, and it consists of low cost, and there is no harmful effect on the environment; In this study, silver nanoparticles are synthesized from AgNO3 using leaf extract of Solena amplexicaulis (Lam.) Gandhi. The leaf extract is mixed with AgNO3 solution, and color change occurs from whitish-yellow to dark brown at room temperature within a few minutes. After incubation, the suspension was centrifuged, and particles were separated and dried. The green synthesized AgNPs were characterized by UV-visible spectroscopy in a maximum wavelength of 393 nm, FTIR, SEM, EDAX, DLS, XRD, and ZETA POTENTIAL; Photocatalytic degradation of Victoria blue or basic blue dye was investigated by green synthesized Ag nanoparticles with solar irradiation technique by biometrically at different time intervals. The UV-visible characteristic peak absorption of Victoria blue solution was 250 nm. The photocatalytic activity at different time intervals [control, treated controls, 30 min, (1, 2, 3, 5, 8, 12, 24, 48, 60, 72) hrs] was collected and decreased the peak intensity and was measured using UV-visible spectroscopy and Fourier Transform Infrared Spectroscopy. Green synthesized Ag nanoparticles effectively degraded the Victoria blue dye solution in total exposure time.
