A new 3D porous Cu(II)-MOF (1) was synthesized based on a ditopic pyridyl substituted diketonate ligand and Cu(OAc)2 in solution, and it features a 3D NbO motif which is determined by the X-ray crystallography. Furthermore, the Pd NPs-loaded hybrid material Pd@Cu(II)-MOF (2) was prepared based on 1 via solution impregnation, and its structure was confirmed by HRTEM, SEM, XRPD, gas adsorption-desorption, and ICP measurement. 2 exhibits excellent catalytic activity (conversion, 93% to >99%) and selectivity (>99% to benzaldehydes) for various benzyl alcohol substrates (benzyl alcohol and its derivatives with electron-withdrawing and electron-donating groups) oxidation reactions in air. In addition, 2 is a typical heterogeneous catalyst, which was confirmed by hot solution leaching experiment, and it can be recycled at least six times without significant loss of its catalytic activity and selectivity.
基于一种双吡啶取代的二酮酸配体和醋酸铜在溶液中合成了一种新型三维多孔铜（II）-金属有机框架（1），其具有通过X射线晶体学确定的三维铌氧结构单元。此外，基于1通过溶液浸渍法制备了负载钯纳米粒子的杂化材料钯@铜（II）-金属有机框架（2），并通过高分辨透射电子显微镜、扫描电子显微镜、X射线粉末衍射、气体吸附-脱附以及电感耦合等离子体质谱测量对其结构进行了确认。2对空气中各种苯甲醇底物（苯甲醇及其带有吸电子和供电子基团的衍生物）的氧化反应表现出优异的催化活性（转化率为93%至>99%）和选择性（对苯甲醛的选择性>99%）。此外，2是一种典型的非均相催化剂，这通过热溶液浸出实验得到证实，并且它可以循环使用至少六次而其催化活性和选择性没有明显损失。
