Abstract: This thesis presents facile methods to effectively deposit metal nanoparticles without capping ligands on substrate. There are two approaches to deposit nanostructured metals on substrates which are two-step reduction of metal precursor by ethylene glycol (EG) solution and solvent-free chemical reduction of metal precursors by EG vapor. The advantages of these methods include the in-situ formation of metal nanostructures onto the substrates with good adhesion, without the presence of binding agents. Several morphologies of nanostructured metals have been developed such as porous platinum, triangular gold nanoplates, dendritic palladium nanostructures. The formation of different morphologies of metal nanostructures is related to the surface energy of the metals. These metal nanostructures have demonstrated high efficiency as a catalyst in fuel cells, dye-sensitized solar cells (DSSCs) with the light conversion efficiency of 8% and excellent anti-bacterial activities against Escherichia coli and Staphylococus epidermidis bacteria after 1 hour of dynamic contact in aqueous media.
