Abstract

original image

Combined with polymer wrapping and layer-by-layer techniques, a noncovalent functionalization method is developed todisperse Pt nanocubes (NCs) onto carbon nanotubes (CNTs). By adjusting therelative ratio of Pt NCs to CNTs, nanotubes with different Pt NC loadings are produced. The composites exhibit excellent electrocatalytic activity towards oxygen reduction.
