Heteroepitaxial growth of platinum nanocrystals on AgCl nanotubes via galvanic replacement reaction.
We demonstrate a general and facile approach for heteroepitaxial growth of Pt nanocrystals on AgCl nanotubes via the galvanic replacement reaction between Ag/AgCl core-shell nanowires and H(2)PtCl(6). These hetero-structured nanotubes exhibit higher electrocatalytic activities for methanol oxidation than conventional Pt/C-nanotube catalysts.
