Abstract
Official abstract text for this publication.
Disclosed herein are dendritically porous three-dimensional structures, including hierarchical dendritically porous three-dimensional structures. The structures include metal foams and graphite structures, and are useful in energy storage devices as well as chemical catalysis.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-dimensional graphite foam comprising a porous graphite core having porous graphite struts radiating from the porous core. 2. The graphite foam of claim 1 , wherein the porous graphite struts comprise porous dendrites. 3. The graphite foam of claim 2 , wherein the porous dendrites have an average pore size from 1-10,000 nm. 4. The graphite foam of claim 3 , wherein the porous graphite core has an average pore size from 1-1,000 μm. 5. The graphite foam of claim 1 , wherein each of the porous graphite struts has a single point of attachment to the core. 6. The graphite foam of claim 1 , wherein the shell level has an average pore size that is less than 30% the pore size of the core level. 7. The graphite foam of claim 1 , wherein the porous graphite core is a multilevel porous core comprising a core level having a first porosity and shell level having a second porosity. 8. The graphite foam of claim 1 , wherein the graphite foam has an areal density of at least 0.01 mg/cm 2 . 9. A supercapacitor comprising the graphite foam of claim 1 .
