Platycladus Orientalis mediated green synthesis of crystalline palladium nanoparticles as a potential and promising nano catalyst in the degradation of dyes for mitigation of environmental pollution

Abstract

In the current study, PdNPs were synthesized in a greener way using Platycladus orientalis leaves extract (PO) as a reducing agent with stabilizing ability. UV–Vis Spectroscopy (UV–Vis), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Transmission Electronic Microscopy (TEM) and Dynamic Light Scattering (DLS) were implicated in the characterization of nanoparticles. The structural and the morphological studies were determined using TEM and XRD analysis while UV–Vis and FTIR studies further confirmed the presence of optical, physical and chemical properties. The images of TEM manifested spherical NPs with an average size of 8 ± 3 nm. Phytochemicals present in the leaf extract enabled the reduction of Pd+2 to Pd0 and also acted as a stabilizing agent. Later, the catalytic property of PdNPs, reduction of dyes like Rhodamine B (RhB), Methyl Orange (MO) and Crystal Violet (CV) was investigated. This green preparation method of making small spherical shaped PdNPs were successfully applied for the reduction of organic dyes.
