Abstract

The composite of gold nanoparticles and mild oxidized MWNTs was used as catalytic cathode of Li-air battery, Au nanoparticles with the diameter of 2.1 nm were decorated by phosphorus ligand and the load weight of Au about 29 wt%. T he catalytic activity of A u/MWNTs was investigated by cyclic voltammetry (CV) and rotating disk electrode (RDE) which revealed that the electron number for ORR was 4.27, 2.98 and 3.77 in acid, neutral and base solution, respectively. This Li-air battery was cycled in DMSO/LiClO4 electrolyte, whose full-discharge capacity turn out to be 15700 mA h/g, which was higher than that of bulk gold and nickel form cathode, and this Li-air battery could cycle for 72 times with the capacity of 1000 mA h/g.
