Abstract

High-quality mesoporous ethylenesilicas were prepared for the first time under acidic conditions using alkylpoly(ethylene oxide) oligomers or polyalkylene oxide triblock copolymers as supramolecular templates. Depending on the synthesis conditions, materials with medium (4-5 nm) and large (8-9 nm) mesopores were obtained. Addition of butanol in conjunction with P123 under acidic condition had a dramatic effect on the pore-size distribution, which became much narrower, indicating the occurrence of a porous system with enhanced ordering.
