Galvanic replacement mediated 3D porous PtCu nano-frames for enhanced ethylene glycol oxidation†
Abstract
Three dimensional (3D) porous PtCu nano-frames with a unique hollow structure were obtained after a galvanic replacement reaction, exhibiting a high normalized mass activity of 23.1 A m−2 μg−1 towards ethylene glycol oxidation with excellent stability. The morphological evolution and catalytic mechanism were detailed.
