摘要

Abstract

The development of green alkylation technology in the production of linear alkylbenzene based on zeolites is highly desired. Herein

a novel nanorod-like mordenite (MOR) zeolite is fabricated by employing a self-designed template

and the morphology of MOR zeolites can be tailored by tuning the alkalinity of the synthesis gel. It's pointed out that the specially designed template is composed of an ethylenediamine functional group and hydrophobic alkyl chains

and the aromatic-aromatic stacking interactions in hydrophobic alkyl chains may facilitate the self-assembly of micellar structures

while the ethylenediamine functional group is matched with building blocks of MOR zeolite

resulting in the formation of nanorod-like MOR zeolite. Moreover

it's demonstrated that the compact stacking nanorodlike particles can be transformed into loose nanorod-like morphology under high alkalinity conditions

in which the Si-O bands are depolymerized

leading to the exfoliation of the stacking nanorod-like particles. The resultant nanorod-like MOR zeolite (MOR-30) displays enhanced accessibility for Brønsted acid sites compared with conventional MOR

achieving over twice the catalytic activity of conventional MOR in the alkylation of benzene with 1-dodecene.
