“…Since they can be produced in great quantities and are repeatable, plant components like roots, leaves, barks, stems, fruits, owers, and seeds are more revered and cherished than microorganisms and enzyme-based synthesis [4]. A well-known medicinal plant called Hydnocarpus pentandra was used to create silver nanoparticles, and their antibacterial and larvicidal properties were investigated [5]. Because of their astounding transdisciplinary uses, metal nanoparticles are transforming science.…”

The present study reports the environment-friendly, energy-efficient, one-pot green synthetic method to synthesize AgNPs from Abrus precatorious fresh leaf extract. Phytochemical screening and chemical profiling tests for the leaf extract revealed the biomolecules that acts as reducing, stabilizing and capping agent. These AgNPs can be used as sensors for toxic heavy metals like Hg 2+, Ni 2+, Cu 2+, Bi 2+, K + and Cr 2+ .Catalytic ability was studied from the dye degradation and nitrophenol reduction. Methylene blue, methyl orange and methyl red dyes were found to degrade drastically with this AgNPs as catalyst. The reaction was carried out for 15minutes, with different concentrations (0.5ml and 2ml) of AgNPs which revealed that more amount of AgNPs catalyst triggered the reaction more easily. 68% of MB dye was degraded with 2ml catalyst and with 0.5ml catalyst 62% degradation efficiency was shown. 34% MO dye was degraded with 2ml catalyst and with 0.5ml catalyst, only 29% degradation was observed. The MR dye exhibited 49% and 42% degradation efficiency for 2ml and 0.5ml catalyst respectively. For reduction of 4-nitrophenol, the catalytic efficiency was calculated to be 66%.
