Abstract

Crystal violet and malachite green, cationic dyes, are widely used in various industries. Water-containing dye molecules affect human health and aquatic life. Here, we synthesized silver-iron oxide nanoparticles using an aqueous extract of kulekhara leaves. The main advantage of this synthesis is that no iron salts were used to prepare Ag-iron oxide nanoparticles. Iron-rich Kulekhara leaves provide iron oxide during the in situ formation of silver nanoparticles. Synthesized Ag-Fe 2 O 3 nanoparticles were characterized by UV-Vis, FTIR, XRD, and STEM-Cs. The dye-degradation studies were performed using synthesized nanoparticles in the presence of sodium borohydride. In the catalytic reaction, the color of crystal violet and malachite green disappeared (100%) within three minutes, and the same results were obtained in their mixtures (1:1 v / v ). The presence of Fe 2 O 3 in AgNPs may boost the rapid reduction in azo bonds due to the higher exposed surface area. The color changes were monitored using UV-Vis spectroscopy. Comparative literature studies showed that the performance of Ag-Fe 2 O 3 is superior regarding the degradation of malachite green and crystal violet. These findings could entice researchers to design and develop various dye degradation using this eco-friendly process.
