Liu, J. ; Aksay, I. A. ; Kou, R. ; Wang, D. H. Mesoporous Metal Oxide Graphene Nanocomposite Materials, 2016. US Patent 9,346,680.




A nanocomposite material formed of graphene and a mesoporous metal oxide having a demonstrated specific capacity of more than 200 F/g with particular utility when employed in supercapacitor applications. A method for making these nanocomposite materials by first forming a mixture of graphene, a surfactant, and a metal oxide precursor, precipitating the metal oxide precursor with the surfactant from the mixture to form a mesoporous metal oxide. The mesoporous metal oxide is then deposited onto a surface of the graphene.
