Solution-Based Evolution and Enhanced Methanol Oxidation Activity of Monodisperse Platinum-Copper Nanocubes

摘要

Platinum nanoparticles (Pt NPs) have been extensively studied because of their unique catalytic properties in various significant applications. It has been shown that the catalytic activity of Pt NPs is highly dependent on the surface atomic arrangements of the particles. For example, previous studies on oxygen reduction in adsorbing acidic solutions show that Pt {100} planes are more active than Pt {111} planes, and the current density measured on Pt nanocubes is higher than that of truncated cubic Pt nano-crystals (NCs). Pt nanocubes have therefore received more attention as electrocatalysts than other morphologies such as multipods and one-dimensional nanostruc-tures.
