Abstract
Abstract
Biogenic green synthesis of gold nanoparticles (Au-NPs) was carried out by utilizing fated waste product of sugarcane industry. Sugarcane bagasse extract was obtained by constant stirring of sugarcane bagasse in aqueous medium for 20 min. Synthesis of gold nanoparticles was carried out at different values of pH of the medium in order to determine the effect of pH on the formation of gold nanoparticles. Fabrication of gold nanoparticles was confirmed by UV–Vis spectroscopic analysis of the reaction mixture and XRD analysis of the sample. FTIR was used to identify different functionalities present in extract responsible for the formation of gold nanoparticles. Biogenic Au-NPs were utilized as a catalyst for the reduction/degradation of nitroarenes and organic dyes such as 4-nitrophenol (4-NP), 4-nitroaniline (4-NA), Congo red (CR), methyl red (MR), brilliant blue (BB), rhodamine B (Rh B) and methyl orange (MO). Kinetics of these reactions proves the efficiency and effectiveness of sugarcane bagasse mediated gold nano-catalysts making them an excellent tool for industrial applications.
