Metal–organic frameworks (MOFs), particularly UiO-66-NH₂, are employed as catalysts in many industrial catalyst applications. As converting catalysts into thin film significantly increases their catalytic properties, we report a general approach to synthesizing MOF thin films (UiO-66-Pyca-CuO). First, functionalization of UiO-66-NH₂ was done with 3-pyridine carboxaldehyde by the postsynthesis method, and then, UiO-66-Pyca was entangled on the surface of copper oxide nanoparticles with a modern strategy (MOF thin film). The morphology and structure of the synthesized UiO-66-Pyca-CuO were determined by using X-ray diffraction, Fourier transform infrared, field-emission scanning electron microscopy, energy-dispersive analysis of X-ray, inductively coupled plasma-mass spectrometry, elemental analyses of CHNOS, temperature-programmed desorption of ammonia, Brunauer–Emmett–Teller, and X-ray photoelectron spectroscopy. We studied the catalytic action of the UiO-66-Pyca-CuO thin film in the synthesis of α-aminonitriles via Strecker reaction. Our studies show that this catalysis can be a suitable catalyst in the synthesis of α-aminonitriles because of having advantages such as using the solvent being environmentally friendly, easy separation of the catalyst (only by picking up the MOF thin film from inside the solution), the reaction at room temperature, high yield, and reusability.

简单新颖的方法合成UiO-66-Pyca-CuO：MOF基金属薄膜作为多相催化剂用于合成α-氨基腈

金属有机框架（MOF），特别是UiO-66-NH ₂ ，在许多工业催化剂应用中用作催化剂。由于将催化剂转化为薄膜显着提高了其催化性能，我们报告了合成 MOF 薄膜 (UiO-66-Pyca-CuO) 的通用方法。首先，通过后合成方法用3-吡啶甲醛对UiO-66-NH ₂进行功能化，然后用现代策略（MOF薄膜）将UiO-66-Pyca缠绕在氧化铜纳米颗粒的表面。采用X射线衍射、傅里叶变换红外、场发射扫描电子显微镜、X射线能量色散分析、电感耦合等离子体质谱、 CHNOS 的元素分析、氨的程序升温脱附、Brunauer-Emmett-Teller 和 X 射线光电子能谱。我们研究了 UiO-66-Pyca-CuO 薄膜在 Strecker 反应合成 α-氨基腈中的催化作用。我们的研究表明，该催化剂具有使用溶剂环保、催化剂易于分离（只需从溶液中拾取MOF薄膜即可）等优点，可以成为α-氨基腈合成的合适催化剂。，反应在室温下进行，收率高，可重复使用。
