Preparation of Hierarchical and Ordered Porous Nanostructured Carbons

The hierarchical and ordered porous nanostructured carbons (HOPNCs) have a very wide application in catalysis, adsorption separation, energy storage and other fields. In this paper, the HOPNCs was prepared through a dual-template method and the resole resin as the carbon precursor,followed by the ethanol solvent evaporation induced self-assembly process. The morphology and microstructure of the as-made products were characterized by SEM, XRD, TEM,and physical adsorption instrument. The results showed that the orderliness of mesoporous carbon materials are significantly enhanced while the ratio of P123/F127 was 1/3,a proper low concentration of template and alcohol solution was helpful to the solvent induced selfassembly formed ordered mesoporous structure of nanocarbons.The as-made HOPNCs have large pores of 200 nm or so, mesopores of 8 and 3 nm or so, the pore volume of 0.2527 cm3/g , the BET surface area of 510m2/g.
