Photocatalytic and antibacterial activity of silver nanoparticles (AgNPs) using palm (Borassus flabellifer L.) water ( Pathaneer )

Abstract

To evaluate the photocatalytic and antibacterial activity of a biologically synthesized AgNPs mediated by palm (Borassus flabellifer) water against human pathogens. It is a potential candidate for preparing nanomedicine for constipation. 1mM of AgNO 3 is prepared and mixed with an appropriate volume of Pathaneer and the reaction was made up to 100ml. The AgNPs were characterized by X-ray diffraction, FT-IR, UV-Vis analysis and HRTEM. The photocatalytic property and the antibacterial activity were carried out for the prepared AgNPs. The powder X-ray diffraction investigation reveals the FCC structure of AgNPs with a crystalline size of 27nm and a lattice strain of 0.4283. FT-IR confirms the presence of Ag + from UV-Vis, the energy band gap was found to be 2.92 eV. HRTEM was used to calculate the diameter of AgNPs as 5-10nm. In Borassus flabellifer, the percentage degradation state of AgNPs was estimated as 87% at 180 minutes. AgNPs derived from Pathaneer have a large impact as antibacterial in the biomedical field. Since the aggressive chemicals are not involved in the preparation of AgNPs, it is used as an alternated biomedicine to reduce the toxicity of AgNPs and the photo degradation efficiency is high hence suitable for solar cells as well.
