摘要：

A composite of graphene-cuprous oxide (Cu2O) was prepared using copper acetate-adsorbed graphene oxide (GO) sheets as precursors. In this composite, in-situ formed Cu2O particles were derived from the adsorbed copper acetate which attached to graphene sheets and prevented the aggregation of the reduced graphene oxide sheets. The as-synthesized Cu2O crystals were cube-like particles distributed randomly on the sheets due to the template effect of GO, consequently forming a graphene-Cu2O cubes composite. A preliminary study on the electrochemical behavior of the graphene-Cu2O composite used as anode material for lithium ion batteries was carried out. (C) 2009 Elsevier Inc. All rights reserved.
