Abstract

original image

Making graphene “bread”: A leavening strategy – involving hydrazine vapor – is used to prepare reduced graphene oxide (rGO) foams with porous and continuously cross-linked structures from freestanding compact GO layered films. Such rGO foams perform excellently as flexible electrode materials for supercapacitors and selective organic absorbents.
