Environmental Friendly Synthesis of Palladium Nanoparticles and its Photocatalytic Activity Against Diazo Dye to Sustain the Natural Source

A facile phyto chemical extracellular synthesis of Palladium nanoparticles (Pd NPs) with the help of starting material Palladium acetate and easily available wild plant Catunaregum spinosa (C. Spinosa) were developed. The phyto chemicals present in the plant acts as secondary metabolites for Pd NPs formation. In most of the industries carcinogenic dyes are released into water bodies in an uncontrolled manner among this Congo red is also released; which said to be a toxic diazo dye. These effluents can play a prominent role in affecting the flora and fauna. In this perspective Pd NPs is synthesized by using C. spinosa root bark aqueous extract in an ecofriendly manner by using bottom-up approach. Further the Pd NPs was monitored by UV-Vis spec and characterized by FT-IR, XRD, TEM, EDAX, Zeta potential. Green synthesized Pd nanomaterials identified as agglomerated spherical shape particles and size average of 47 +/- 2 nm by microscopical analysis. Further the synthesized Pd NPs were investigated against the homogenous catalytic degradation Congo red results in 83%.
