  • Porous graphene oxide materials
    Patent number: 9180442
    Abstract: A method of preparing a porous graphene oxide material. The method includes the steps of: (1) preparing graphene oxide sheets from graphite at 40 to 170° C.; (2) providing a graphene oxide suspension containing the graphene oxide sheets; (3) heating the graphene oxide suspension with a base at 25 to 300° C. for 0.1 to 48 hours to obtain base-treated graphene oxide sheets; and (4) heating a mixture of the base-treated graphene oxide sheets and an acid at 25 to 300° C. for 0.1 to 48 hours to yield the porous graphene oxide material. Also disclosed are novel porous graphene oxide materials and methods of using these materials as catalysts.
