Monolithic Macroporous-Mesoporous Carbon Using Ionic Liquids as Carbon Source
Abstract:
A facile approach is employed for the preparation of hierarchically porous structures monolithic ordered macroporous-mesoporous silica materials (OMS) using the commercially available and cheap polyurethane (PU) foam as monolithic template, triblock copolymer P123 (EO20PO70EO20) as structure-directing agent and tetraethyl orthosilicate (TEOS) as silica source, then monolithic ordered macro porous-mesoporous carbon materials (OMC) is synthesized by using monolithic ordered macroporous-mesoporous silica materials as hard template and ionic liquids as the carbon source. The silica and carbon monoliths possess uniform pore sizes (3.74-3.84 nm) and ordered mesostructure.
