In this paper, Physical and chemical structures of pitch based high surface area activated carbon(PHAC) were studied by ASPP2000, XPS,SEM and TEM. Pore size distribution and pore structural parameters of PHAC were determined by N_2 adsorption(at 77K).是什么意思_In this paper, Physical and chemical structures of pitch based high surface area activated carbon(PHAC) were studied by ASPP2000, XPS,SEM and TEM.
