Abstract
Methods of producing fibrous solid carbon forests include reacting carbon oxides with gaseous reducing agents in the presence of a catalyst having a predetermined grain size to cause growth of fibrous solid carbon forests upon a surface of the metal. The fibrous solid carbon forests are substantially perpendicular to the surface of the metal thus creating the “forests”. A bi-modal forest composition of matter is described in which a primary distribution of fibrous solid carbon comprises the forest and a secondary distribution of fibrous solid carbon is entangled with the primary distribution. A reactor includes a catalyst, a means for facilitating the reduction of a carbon oxide to form solid carbon forests on a surface of the catalyst, and a means for removing the solid carbon forest from the surface of the metal catalyst.
