  1. 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
