摘要

Abstract

Design and synthesis of low cost and efficacious industrial catalyst for the oxidation of styrene has been an important research project. Herein

ZSM-5 zeolite containing tetrahedral vanadium (V) and Brønsted acid sites (V-H-ZSM-5) was prepared

and identified by characterizations such as XRD

SEM

UV-vis

-TPD

-TPR N

-adsorption/desorption and FTIR. V-H-ZSM-5 performed extremely enhanced catalytic activity for the oxidation of styrene with 30% H

at 40℃. Moreover

in-situ

FTIR spectrum was used to investigate the catalytic mechanism. The results demonstrate that Brønsted acid site could not only increase the adsorption concentration of styrene in the micropores of V-H-ZSM-5

via

the π complex interaction between double bond of styrene and Brønsted acid sites

but also increase the oxidation potential of H

. The synergetic action of tetrahedral vanadium (V) and Brønsted acid enhanced the catalytic activity for the oxidation of styrene with 30% H

. Impressively

V-H-ZSM-5 performed high reusability within f

ive runs at a low reaction temperature (40℃) for the first time.
