[en] Hierarchically porous monolithic carbon represents an ideal platform for various types of studies - from the development of new characterization techniques (thermoporometry), through the solution of surface oxidation kinetics of carbon, testing of adsorption phenomena (gases, solutions), searching for surface treatment options (introduction of heteroatoms) to carbon use as carriers of catalytically active nanoparticles (metals, TiO₂). The possibility of pore size control in such materials (especially mesopores in the range of 10-50 nm) is a completely unresolved issue. (authors)
