Abstract
Carbon nanotube (CNT) hybrid materials and methods of making such materials. A carbon nanotube (CNT) hybrid powder material includes a mesh of CNTs intimately interspersed with particles of a second material. In an example the material includes a blend that itself includes particles of a metal oxide supported catalyst and particles of a second material, and a mesh of CNTs is grown on the supported catalyst in the blend. The mesh of CNTs is effective to disperse the particles of the second material.

A method for creating a carbon nanotube (CNT) hybrid powder material, comprising:
- forming a blend of a powder catalyst material and a separate different powder carbon material;
- wherein the catalyst material comprises a plurality of metal-oxide supported metal catalyst grains, each catalyst grain formed from a number of elementary catalyst particles grouped to form the catalyst grain;
- wherein the different powder carbon material comprises a plurality of agglomerates of a second material that comprises carbon, each agglomerate formed from multiple particles of the second material;
- growing meshes of CNTs directly on the elementary catalyst particles, to create the CNT hybrid powder material;
- wherein the CNTs of the mesh physically separate at least some of the elementary catalyst particles from the catalyst grains;
- wherein the CNTs of the mesh physically separate at least some of the particles of the second material from the agglomerates of particles of the second material;
- and
- wherein at least some of the particles of the second material are separate from and not touching either the catalyst particles or the CNTs.
