Abstract
The present patent application discloses a novel sol-gel process to synthesize a nano-porous solid carbon material—suitable for use in electrodes in energy storage applications—from a combination of liquid reagents that undergo a polymerization reaction to form a matrix.
Claims20
A method of producing nano-porous carbon, comprising:
- a) mixing a liquid carbonyl-containing carbon source with a liquid acidic polymerization catalyst until a solid catalyst-carbon matrix forms;
- b) heating the solid catalyst-carbon matrix;
- and
- c) etching the solid matrix to remove the catalyst from the carbon matrix to produce a network of pores in the carbon.

A method for the production of nano-porous carbon, comprising:
- a) mixing a liquid furfuryl compound with a liquid acidic polymerization catalyst until a solid catalyst-carbon matrix forms;
- b) heating the solid catalyst-carbon matrix;
- and
- c) etching the solid matrix to remove the catalyst from the carbon matrix to produce a network of pores in the carbon,
- wherein the rate of formation of the solid catalyst-carbon matrix is controlled by dilution of the liquid furfuryl compound with a less reactive liquid carbonyl-containing carbon source.
