Abstract

Novel monolithic mesoporous silica was synthesized with a new SDA (Structure-Directing Agent) of PE6400 (EO13PO30EO13). The monolithic silica was found possessing special “oriented block” structure at nano-scale where pore channels' orientations were the same in a single block but not always the same in different blocks. Pore channels of a single oriented block were well ordered hexagonally oriented. Moreover, the average pore diameter, the average wall thickness, the specific surface area and the pore volume of the obtained monolithic silica were 3.5 nm, 3.3 nm, 777.5 m2/g and 0.44 m3/g, respectively.
