Abstract

The formation of gold nanoparticles in our optimized synthesis is achieved through reduction of tetrachloroauric acid in 2 - (N - morpholino)ethanesulphonic acid (MES) buffered glucose and stabilization by starch at room temperature. The formation has been followed by measuring the electrochemical potential, conductivity, pH, turbidity, UV - Vis extinction , core size and hydrodynamic diameter . The synthesized AuNPs have been employed as core particles in advanced core - shell structures with highly porous platinum nanoparticle coating or copper oxide shells. These hold poten- tials as effective catalysts in fuel cells and methanol reformers.
