Abstract: Three-dimensional (3D) printing of graphene materials and methods and apparatuses for making same. In some embodiments, combined metal powder and carbon growth sources (such as powder Ni and sucrose) are utilized in the 3D printing process. In other embodiments, metal powders with binders (such as powder Ni and a polymer bases binder) are utilized in the 3D printing process. The metal in the resulting 3D printed composite material can then be etched or otherwise removed yielding the 3D printed graphene materials.

Abstract: Provided are: a method for easily producing a ZTC material, wherein in place of raw materials of conventional carbon materials, sugars such as glucose, and crosslinkable hydrocarbons such as DVB are used as a carbon source material; a pellet comprising a ZTC; and a method for producing the same. This method for producing a zeolite-templated carbon material is used, wherein the method involves introducing sugars or the like into a surface and pores of zeolite, and heating the same to carbonize the sugars, and then dissolving and removing the zeolite.
