Synthesis, characterization and antifungal activities of eco-friendly palladium nanoparticles.

ABSTRACT: Palladium is a versatile catalyst, but the synthesis of palladium nanoparticles (PdNPs) is usually attained at a high temperature in the range of 160 °C to 200 °C using toxic reducing agents such as sodium borohydride. We report the synthesis of PdNPs using a low-cost and environmentally-friendly route at ambient temperatures. Quercetin diphosphate (QDP), a naturally-derived flavonoid, was employed as a reducing, capping, and stabilizing agent. The effect of temperature was optimized to produce perfectly spherical PdNP nanoparticles with sizes ranging from 0.1 to 0.3 microns in diameter. At relatively higher concentration of QDP, significantly smaller particles were produced with a size distribution of 1-7 nm. Perfectly spherical PdNP nanoparticles are a rare occurrence, especially under a
