Activated carbon presents some peculiarities: it is a non-crystalline material (amorphous), is a non-stoichiometric solid with variable composition, and it is opaque to most wavelengths and species used in a characterization laboratory. The chemistry of carbon is extremely complex (Schlogl, 1997; Do, 1998); the main reason for this

Activated carbon - Wikipedia

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes replaced by active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.

How to Make Activated Charcoal

The carbon + steam reaction results in producing hydrogen gas and carbon monoxide (C+H2O=H2 +CO). As the carbon monoxide gases off it takes carbon atoms with it. Typically 3 pounds of raw charcoal will produce 1 pound of activated charcoal. This is a perfect example of the saying "Less is More". Less carbon atoms yields More internal space.
