Direct fabrication of mesoporous zeolite with a hollow capsular structure

Abstract

We report the direct fabrication of mesoporous zeolite with a hollow spherical/ellipsoidal capsule structure by using conventional TPAOH and CTAB as soft micro- and mesopore generating templates; the mesoporous zeolite shows a high surface area of 717 m(2) g(-1) and small mesopore size of around 3 nm.
