Biosynthetic processes for palladium nanoparticles would be more useful if nanoparticles were produced using plants or their extracts or seaweeds and in a controlled manner according to their size, dispersity and shape, however reduction of palladium chloride using plant extracts or marine alga has not been explored much. Aqueous extract of Sargassum wightii has been used for the bioreduction of Pd2+ to Pd0. The absence of absorbance band above 300 nm revealed the complete reduction of Pd2+ ions. Using Fourier transform infrared spectroscopy (FTIR functional groups involved in the synthesis were identified. Morphology of palladium nanoparticles in the colloidal solutions were analyzed using Scanning Electron Microscopy (SEM) and their size distribution were also investigated using HR-TEM.
