Abstract: Carbonaceous composite with hierarchically porous structure is prepared by using Mg(OH)2 pre-filled PAN-based membrane precursor for the first time.The prepared carbonaceous composite contains 54.1% of C,26.8% of O,6.2% of N and 6.5% of Mg.The composite is used as electrode material of super capacitor and dye adsorbent.As it is used to make electrode material for super capacitor,the specific capacitance reaches 236 F·g-1 at a scanning rate of 1 A·g-1,and about 206 F·g-1 at a scanning rate of 10 A·g-1.The retention rate of specific capacitance is as high as 87%.Such an excellent ratio performance is related to the hierarchy of porous structure.As the carbonaceous composite is used as a dye adsorbent,it shows a high adsorption capacity to methyl orange.The saturated adsorption capacity can reach about 1,170 mg·g-1 when the mass content of methyl orange is 800 μg·g-1.The present study provides a simple method to prepare the novel carbonaceous composite for different applications.
