Abstract
A facile wet chemistry method was developed for the synthesis of PtCu bimetallic alloy nanotubes with controllable composition and porous surfaces by employing Te nanowire as a hard template. Due to the synergetic effect among the components as well as their one-dimensional porous nanostructure, the PtCu nanotubes present enhanced electrocatalytic activity and durability for oxygen reduction reaction in acid solution. The mass activity and specific activity of Pt76Cu24 reach 0.41 A mg(Pt)-1 and 0.83 mA cm(-2), and are about 3 and 5 times higher than that of Pt/C catalysts. The bimetallic alloys could be considered as an excellent candidate for electrocatalysts and other potential applications.
