标题：tuning ion complexing for rapidly preparing hollow ag/pt nanowires with high activity toward methanol oxidization reaction
abstract: hollow pt-based nanowires (nws) have important applications in catalysis. their preparation often involves two-step process in which m (m=ag, pd, co, ni) nws are prepared and subsequently subjected to galvanic reaction in solution containing pt precursor. it is challenging to achieve simple one-step preparation, because the redox potential of pt(iv)/pt or pt(ii)/pt to pt is high, and therefore, pt atoms always form first. this work demonstrates that appropriate ph can decrease the redox potential of pt(iv)/pt and allows one-step preparing high quality hollow pt-ag nws rapidly (10 min). moreover, it is easy to realize large-scale preparation with this method. their composition can be adjusted readily for optimizing performance in electrocatalytic methanol oxidization reaction (mor). compared with commercial pt/c, nws with appropriate ag/pt exhibit high stability, activity and co tolerance ability.
