1. A method of forming a binder-free, mesoporous, graphitic multi-layer carbon composite structure, the method comprising:
disposing a precursor composition on a substrate, which comprises a first polymer, and the precursor composition comprising:
a porogen comprising a block copolymer;
a support phase precursor component comprising a metal alkoxide, a metal oxide, or a polyoctahedral silsesquioxane;
a carbon component comprising phenol formaldehyde resin, glucose, cellulose, or 4-hydroxybenozic acid; and
a metal or metal oxide nanoparticle selected from aluminum, magnesium, chromium, tin, silver, titanium, gold, silicon, silicon carbide, iron, iron oxide, copper, nickel, palladium, platinum, ruthenium, rubidium, alloys thereof, or mixtures thereof;
irradiating the disposed precursor composition with sub-millisecond light pulses so as to carbonize the precursor composition, decompose the porogen, and convert the carbon component to a graphitic material to form a binder-free, mesoporous, graphitic multi-layer carbon composite structure,
wherein the graphitic material is generated during irradiation, and the precursor composition is directly converted to the binder-free, mesoporous, graphitic multi-layer carbon composite without any addition of, polymer, or binder materials.
