The composition includes a porogen component, a carbon component, and a catalyst component. The method further includes irradiating the precursor composition to form the carbon composite structure.
Claims20
A method of forming a binder-free, mesoporous, graphitic multi-layer carbon composite structure, the method comprising:
- disposing a precursor composition on a substrate, the precursor composition comprising:
- a porogen component comprising a polymer;
- a carbon component comprising phenol formaldehyde resin, glucose, cellulose, or 4-hydroxybenozic acid, brown sugar, barley sugar, caramel, cane sugar, corn syrup, starch, molasses, molasses raffinate, glucan, galactan, xylan, sugar waste product, activated carbon, carbon black, carbon fiber, carbon honeycomb or plate structure, aerogel carbon film, pyrolysis char, (C1-C40) alkane, (C1-C40) alkene, (C1-C40) alkyne, (C1-C40) aryl or a combination thereof;
- and
- a metal or metal oxide nanoparticle comprising 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 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.
A method of forming a binder-free, mesoporous, graphitic multi-layer carbon composite structure, the method comprising:
- disposing a carbon-containing precursor composition on a substrate that comprises a metal, the precursor composition comprises:
- a porogen that is a block copolymer;
- and
- phenol formaldehyde resin, glucose, cellulose, or 4-hydroxybenozic acid;
- and
- at least one of gold nanoparticles coated with 4-mercapto-phenol or iron/iron oxide nanoparticles coated with 4-hydroxybenzoic acid;
- irradiating the disposed precursor composition with sub-millisecond light pulses so as to carbonize the precursor composition, decompose the porogen, and convert the phenol formaldehyde resin, glucose, cellulose, or 4-hydroxybenozic acid to a graphitic material to form a binder-free, mesoporous, graphitic multi-layer carbon composite structure.
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 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.
