Pseudomorphic synthesis of mesoporous zeolite Y crystals
Résumé
A simple method for the conception of mesoporous zeolite Y crystals with a narrow intracrystalline mesopore size distribution is reported. It involves the pseudomorphic transformation of parent zeolite crystals by recrystallisation in the presence of surfactants, and leads to two interconnected pore systems in the zeolite crystals.
