A metal oxide anchored graphene and carbon nanotube hybrid foam can be formed via a two-step process. The method can include forming at least one graphene layer and a plurality of carbon nanotubes onto a surface of a porous metal substrate by chemical vapor deposition to form a coated porous metal substrate, and depositing a plurality of metal oxide nanostructures onto a surface of the coated porous metal substrate to form the metal oxide anchored graphene and carbon nanotube hybrid foam.

Methods of fabricating a graphene film are disclosed. An example method can include providing a substrate, heating the substrate between about 600&#xb0; C. and about 1100&#xb0; C. in a chamber, and introducing a carbon source into the chamber at a temperature between about 600&#xb0; C. and about 1100&#xb0; C. for about 10 seconds to about 1 minute. The method can further include cooling the substrate to about room temperature to form the graphene film Methods of fabricating pillared graphene nano structures and graphene based devices are also provided.
