ABSTRACT

In this work, nanoporous carbons (NPCs) were prepared by the self-assembly of polymericcarbon precursors and block copolymer template in the presence of tetraethyl orthosilicateand colloidal silica. The NPCs’ pore structures and total pore volumes were analyzed by referenceto N2/77 K adsorption isotherms. The porosity and elemental mercury adsorption ofNPCs were increased by activation with carbon dioxide. It could be resulted that elementalmercury adsorption ability of NPCs depended on their specific surface area and micropore fraction.
