In this study, silver nanoparticles (B-AgNPs) derived from banyan aerial root extract were successfully synthesized and applied as an efficient catalyst for the degradation of aniline blue dye. The B-AgNPs exhibited high catalytic efficiency and long-term stability, making them a promising candidate for industrial wastewater treatment in the dye industry.
Herein we are reporting the reductive degradation of aniline blue dye using banyan aerial root extract derived silver nanoparticles (B-AgNPs) as catalyst. We have synthesized B-AgNPs by green root method. The characterization of synthesized B-AgNPs was done using HR-TEM, UV-vis spectral, Total Organic Carbon, FT-IR and XRD techniques. The SPR band was obtained around 445 nm. Crystal structure of B-AgNPs was observed using XRD pattern. The stability of 25.6 nm sized B-AgNPs was found to be beyond four months. Finally, the synthesized B-AgNPs was applied as a photocatalytic degradation catalyst of aniline blue dye with NaBH4 as a reducing agent. The catalytic activity was systematically monitored using UV-Visible spectrophotometry. The catalytic efficiency was calculated to be 91.76%. Moreover, the synthesized B-AgNPs were used as a catalyst for the efficient degradation of dye effluent in the dye industry. We have applied the synthesized B-AgNPs as a catalyst for the effective degradation of industrial dye wastewater. Moreover, we have proposed the possible degradation mechanism.
