▎ 摘　　要

A new electrode material composed of graphene oxide (GO) and pristine graphene (PG) was simply fabricated, and a very fast electron transfer kinetics on GO/PG electrodes was exhibited. This improved electrochemical performance of the GO/PG composites should be ascribed to a unique structure formed when GO combined with PG nanosheets serving as patches. (C) 2014 Elsevier B.V.
