Preparation of graphene comprises reacting graphite oxide and sulfuric acid under normal pressure or negative pressure.

JIN X, HONG Y

Preparation of porous graphene for aluminum-air cell involves carrying out high temperature heat treatment to graphite oxide precursor in muffle furnace, ultrasonically dispersing in alcohol to obtain black suspension liquid, and washing.

ZHOU Y, LIU C

Preparing graphene material involves adding graphene oxide to obtain suspension of graphene oxide to disperse medium, spray drying the suspension to obtain graphene oxide particles, and reducing the graphene oxide particle by atmosphere.

HONG M, WANG Y

Preparing graphene used for preparing titanium dioxide-graphene nano-composite material, by reducing dispersive graphite oxide in inert solvent to form graphene-containing reaction mixture, and isolating graphene from reaction mixture.
