Bottom-up synthesis of palladium nanoparticles: Kinetics effect and catalytic activity

Abstract

Green nanotechnology is the term used to describe the ecologically responsible process of manufacturing PdNPs. It is an economical, safe, extensively utilized technology that is also good for the environment. In this work, Pd ions used for the bio-reduced to PdNPs using leaf extract from the Rosa damascena plant. The transmission electron microscopy of the PdNPs was analyzed at approx. 50 nm. This study examines the consequences of three key specifications on the environmental production of PdNPs. Temperature, pH, and volume of leaf extract are significant process factors. A leaf extract volume of 5 ml, pH of 4, and a temperature of 60 °C were more suitable for the maximum production of PdNPs. The volume of leaf extract, pH, and temperature were analyzed at 300 nm, 320 nm, and 350 nm using a UV–Vis spectrum to characterize PdNPs at the SPR band. Within the context of C–C cross-coupling processes, such as Mizoroki-Heck and Suzuki-Miyaura reactions the catalytic activity of PdNPs was examined at mild reaction conditions. For the purpose of characterizing the isolated product, 1H NMR was used. The PdNPs demonstrated a high level of catalytic activity and were able to provide conversion of the products that were being converted.
