Plant mediated biological synthesis is one of the green approaches that has attracted the attention of the researchers.

This experiment revealed the biological synthesis of palladium nanoparticles (PdNPs) using aqueous bark extract of the plant named Bauhinia variegata(Kaanchnar).

Biomolecules present in the plants act as a reducing agent as well as capping agent by which PdII metal gets reduced, leading to the formation of PdNPs. XRD revealed the crystalline PdNPs posses face-centered cubic structure with an average size about 2.87 nm. FTIR showed that biomolecules like proteins are responsible for the reduction of metal ions and form encapsulating layer on the metal ions (capping of PdNPs).

Themorphological study showed an aggregated irregular shape using FEG-SEM. Elemental composition and purity of the PdNPs were analyzed by EDS. HR-TEM revealed …
