摘要:The paper presented an alloying/dealloying process for the fabrication of hierarchically porous alloy films (HPAFs). The fabrication process involved electrodeposition of copper on the substrate, annealing to produce new alloy phases, and selective dissolution of copper from the surface. Scanning electron microscopy (SEM) images suggested that the HPAFs were composed of large-sized ligament-channels structures (several micrometers) coupled with small-sized ligament-pores (tens nanometers) interpenetrating the big architectures. Energy dispersive X-ray analysis spectra (EDS) revealed the nonuniform distribution in chemical composition of the large-sized ligament-channel structures. Moreover, we demonstrated that the resulting materials showed catalytic activity for methanol electro-oxidation in alkali solution. We believe that the resulting HPAFs electrode is prospective in the fields of catalysis, sensors, and so on. (C) 2011 Elsevier B.V. All rights reserved.
