Specific surface area in total (S _BET), of nanopores (S _micro), mesopores (S _meso), macropores (S _macro), and respective specific pore volumes (V _p, V _micro, V _meso, V _macro). R _p,V represents the average pore radius determined from the differential pore size distributions with respect to the pore volume
