• Carbon monolith
• Porous concrete
• Template

The preparation of carbon monoliths with defined shape and hierarchical pore system has been investigated. A template assisted route was applied using porous concrete as the template. The synthesis route was combined with a one pot chemical activation using phosphoric acid and zinc chloride, respectively, as the activating agents. As the template caused the formation of primary macropores the activation created a secondary system of micropores which resulted in a significant increase of the specific surface area up to about 1400 m(2) g(-1). The material was characterized by means of mercury intrusion, helium pycnometry, and nitrogen adsorption at 77 K.
