Title: BSMV as a Biotemplate for Palladium Nanomaterial Synthesis

Abstract

BSMV was successfully used as a biotemplate to form high quality Pd nanorods in the absence of an exogenous reducer. The nanorods synthesized were uniform with controllable diameters. X-ray absorption spectroscopy (XAS) studies were used to elucidate the fundamental rate law for Pd reduction mediated by the virus surface. The technique was subsequently combined with UV-Vis spectroscopy to decouple the processes of adsorption and reduction of Pd precursor. Adsorption was best modeled by a multi-step Langmuir isotherm. It was deduced that the 1st local isotherm is governed by electrostatically driven adsorption, which is then followed by sorption driven by covalent affinity of metal precursor molecules for amino residues. Finally, study of the BSMV-Pd particles using USAXS enabled the characterization of all length scales in the synthesized particles.
