Title:
GLUTARIC ACID SELECTIVE POLYACID CATALYST BASED ON MICRO-MESOPOROUS ZR-MOF MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/247214
Kind Code:
A1
Abstract:
The present invention relates to the technical fields of nanomaterials and catalysis, and in particular, to a glutaric acid selective polyacid catalyst based on a micro-mesoporous Zr-MOF material, a preparation method therefor and an application thereof. The preparation method specifically comprises the preparation of a precursor MOx@UiO-66, the preparation of an intermediate MOx@UiO-66@UiO-bpy, and the preparation of a catalyst MOx@UiO-66@MOx@UiO-bpy. The present invention also provides an application of the micro-mesoporous Zr-MOF polyacid catalyst in a solvent-free cyclopentene green catalytic oxidation reaction for the directional preparation of glutaric acid. The micro-mesoporous Zr-MOF polyacid catalyst in the present invention has functions of micro- and mesopores, transition metal Mo/W oxide active species, and acid, is a multifunctional catalyst, accelerates the diffusion of reactants and products, inhibits leaching of active species, has a glutaric acid selectivity up to 93.6%, is easy to separate and recycle after reaction, still has a glutaric acid selectivity reaching 92.8% when being repeatedly used for 10 times, and has a good application prospect.
