摘要
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 H2PtCl6. These hetero-structured nanotubes exhibit higher electrocatalytic activities for methanol oxidation than conventional Pt/C-nanotube catalysts.
