Beschreibung
Zusammenfassung:	The invention discloses a metal organic framework ZIF-90-coated UIO66-NH2 Pickering emulsion based on a core-shell structure and application of the metal organic framework ZIF-90-coated UIO66-NH2 Pickering emulsion, and belongs to the field of catalytic synthesis. According to the invention, ZIF-90 and UIO66-NH2 is adopted as an emulsifier, and toluene and water are adopted as solvents at the same time, so that the ZIF-90 and UIO66-NH2 stable Pickering emulsion is formed. The preparation method of the Pickering emulsion with stable ZIF-90 and UIO66-NH2 provided by the invention is simple, and the Pickering emulsion with stable ZIF-90 and UIO66-NH2 shows relatively high catalytic capability and stability in a Deacetazilation-Knoevenagel cascade reaction. 本发明公开一种基于核壳结构的金属有机框架ZIF-90@UIO66-NH2皮克灵乳液及其应用，属于催化合成领域。本发明采用ZIF-90@UIO66-NH2作为乳化剂，同时以甲苯和水作为溶剂，形成ZIF-90@UIO66-NH2稳定的皮克灵乳液。本发明涉及的ZIF-90@UIO66-NH2稳定的皮克灵乳液制备方法简单，并在并在Deacetalization-Knoevenagel串联反应中表现出较高的催化能力和稳定性。
