Abstract

The invention relates to a method for synthesizing an OMS-2 manganese oxide octahedral molecular sieve. By special solvent properties and reductibility of an ionic liquid, the OMS-2 manganese oxide octahedral molecular sieve with specific appearance and physicochemical performance can be synthesized. During the synthesis process, the ionic liquid is used as a reaction medium and a reducing agent to be uniformly mixed with permanganate and sylvite; crystallization is carried out at a certain temperature for a certain time; and washing and drying are then carried out to obtain the OMS-2 manganese oxide octahedral molecular sieve. The manganese oxide octahedral molecular sieve can be used as a catalyst for a plurality of selective oxidation reactions.

Description

technical field

[0001] The invention discloses a method for synthesizing an OMS-2 type manganese oxide octahedral molecular sieve, that is, a method for synthesizing an OMS-2 type manganese oxide octahedral molecular sieve by using an ionic liquid as a reaction medium and a reducing agent. Background technique

[0002] As an important industrial raw material, manganese oxide is widely used in the preparation of battery cathode materials, magnetic materials and oxidation reaction catalysts. Manganese oxide for industrial use is obtained by mining pyrolusite and deep-sea manganese nodules. However, the purity of manganese oxide ore is not high, the crystal phase is complex, and the crystallinity is poor, so chemists have been working on the synthesis of manganese oxide with specific crystal phase and morphology. Since 1993, researchers such as Suib S.L. have successively reported a series of manganese oxide octahedral molecular sieves with a regular one-dimensional pore struc...
