摘要

Abstract

In this work

the catalytic performance of vanadia-molybdena loaded on TiO

MgO

ZSM-5

NaY and Mordenite was investigated in the selective oxidation of 2-methylnaphthalene (2-MN) to 2-naphthaldehyde (2-NA). Results show that strong interactions between supports (TiO

ZSM-5) and active components can promote the dispersion of active component. Monolayer VO

and MoO

are the main form on the catalyst surface

which is beneficial to the 2-NA selectivity. However

the corresponding weak interactions between Mordenite and active components may lead to the production of oxide crystals and the separation of active components

thus reducing the 2-NA selectivity. Due to the high Na content

new crystal NaVMoO

forms on the NaY surface

which is inactive in the reaction. For V-Mo/TiO

V and Mo can be inserted into the TiO

lattice

changing the electronic structures of active components and support and improving the activity of surface oxygen species. This investigation highlights an important consideration on supports properties when designing supported catalysts.
