charcoal
A black, porous, carbonaceous material, 85 to 98 percent carbon, produced by the destructive distillation of woodand used as a fuel, filter, and adsorbent.
graphite
A soft crystalline allotrope of carbon, composed of graphene layers, having a steel-gray to black metallic luster and agreasy feel, used in lead pencils, lubricants, paints and coatings, and fabricated into a variety of forms such as molds,bricks, electrodes, crucibles, and rocket nozzles.
graphene
A monolayer of carbon atoms having a hexagonal lattice structure and constituting a basic structural element ofgraphite, fullerenes, and carbon nanotubes.
activated carbon
Activated carbon is a kind of black porous solid carbon, by coal by grinding, molding or with uniform coal particles by carbonization, activation of production.
Charcoal is amorphous and porous carbon, it contains almost no graphitic phase and it may contain patcially carbonized organig substances as well as tar and minieral all of these varying tremendously with the source used to generate the Charcoal. Activated carbon is similar but it has been prepared from substrates carefully selected to yield a very high porosity. Some forms come from carbonizing carbohydrate substrates like starch or celulose yielding very low mineral content.
Graphene is exclusively a single layer of carbon atoms in a hexagonal arrangement with sp2 hibridization. Graphite is a stack of a large number of layers of graphene by virtue of the interaction of a p orbital residing on each carbon atom, having the z axis perpendicular to the graphene layer. There are other forms of carbon like soot which contains graphene fragments, nanotubes ,buckyballs among other carbon forms.
