Abstract
The present patent application discloses a method of producing nano-porous carbon, comprising mixing furfuryl alcohol or its fast-polymerizing derivatives with an aluminum-based solid polymerization catalyst, heating the mixture until a solid catalyst-carbon matrix forms, heating again under inert atmosphere and etching the powder to remove the matrix to produce a network of pores in the nano-porous carbon. The application further provides a method for making of fabricating tailor-made nano-porous carbon electrodes.
Claims18
A method of producing a nano-porous carbon, comprising:
- a) mixing a liquid compound containing a furfuryl group with an aluminum-based solid polymerization catalyst powder to form a mixture;
- b heating the mixture until a polymerized solid catalyst composite forms;
- c) heating the polymerized solid/catalyst composite under inert atmosphere to form a catalyst/carbon matrix;
- and
- d) etching the catalyst/carbon matrix to remove the catalyst from the catalyst/carbon matrix to produce a the nano-porous carbon.
A method of fabricating a nano-porous carbon electrodes, comprising:
- a) diluting a furfuryl group containing liquid compound with a liquid carbonyl-containing carbon source to form a solution, wherein the liquid carbonyl-containing carbon source is at least one of an acetone, ionone, benzophenone or acetylacetone;
- b) mixing a polymerization catalyst, to the solution to make a mixture;
- c) pouring the mixture into a mold;
- d) heating the mixture in the mold to f orm a solid polymer/catalyst composite;
- e) unmolding the solid polymer/catalyst composite;
- f) heating the solid polymer/catalyst composite to form a carbon/catalyst composite;
- g) etching the carbon/catalyst composite to remove the catalyst from the carbon/catalyst composite to produce the nano-porous carbon;
- and
- h) activating the nano-porous carbon, wherein the activating comprises heating under a controlled atmosphere wherein the controlled atmosphere is one of a CO2 or steam.
