High performance electrocatalyst: Pt-Cu hollow nanocrystals

摘要

Pt-Cu hollow nanocrystals with excellent electrocatalytic activities were produced by a one-pot synthesis method. The catalytic activities of these nanocrystals toward methanol electro-oxidation were studied by cyclic voltammetry (CV). The Pt-Cu hollow nanocrystals exhibited higher catalytic activity for methanol oxidation than commercial Pt black and Pt/C.
