Synthesis of highly ordered nanoporous carbon molecular sieves from silylated MCM-48 using divinylbenzene as precursor

Calcined pure silica MCM-48 is modified by silylating its mesopores with trimethylsilyl chloride; such pore modification along with polymerization and carbonization of divinylbenzene as a carbon precursor is found to be a very efficient way of fabricating highly ordered carbon molecular sieves with three-dimensionally interconnected uniform pore arrays, greatly improving structural integrity and thermal stability.
