Abstract A composite β-mCoPc/Cu-BDC is developed by decorating Cu-BDC with β-m-phthalocyanine cobalt (β-mCoPc) and systematically investigated by a series of combined analyses of X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), N2 physisorption measurements, scanning electron microscopy (SEM), transmittance scanning electron microscopy (TEM) and thermogravimetry analysis (TGA). Due to the desirable properties of Cu-BDC and β-mCoPc, such as the conjugated MOFs skeleton, the acidity of the central ion and large specific surface area and porosity of the materials, etc., β-mCoPc/Cu-BDC is successfully applied as the catalyst for the oxidation of benzyl alcohol to benzaldehyde. Significantly, an enhanced catalytic performance especially with a best conversion rate of 61% at an optimal molar ratio of 0.24:1 of β-mCoPc:Cu-BDC can be confirmed for β-mCoPc/Cu-BDC composites catalyst in comparison with catalysis by only β-mCoPc and Cu-BDC. Our work provides an effective strategy via preparing a MOF based composite catalyst to realize the selective oxidation of benzyl alcohol to benzaldehyde. Graphical Abstract

β-mCoPc/Cu-BDC 复合物用于将苯甲醇氧化成苯甲醛

摘要 以 β-间酞菁钴 (β-mCoPc) 修饰 Cu-BDC，并通过 X 射线粉末衍射 (XRD)、X-射线光电子能谱 (XPS)、傅里叶变换红外 (FT-IR)、N2 物理吸附测量、扫描电子显微镜 (SEM)、透射扫描电子显微镜 (TEM) 和热重分析 (TGA)。由于Cu-BDC和β-mCoPc的共轭MOFs骨架、中心离子的酸性以及材料的大比表面积和孔隙率等理想特性，β-mCoPc/Cu-BDC被成功地制备出来。用作苯甲醇氧化成苯甲醛的催化剂。显着地，与仅通过 β-mCoPc/Cu-BDC 复合催化剂相比，β-mCoPc:Cu-BDC 的最佳摩尔比为 0.24:1 时，可以证实具有增强的催化性能，特别是在 61% 的最佳转化率-mCoPc 和 Cu-BDC。我们的工作通过制备基于 MOF 的复合催化剂实现苯甲醇选择性氧化为苯甲醛提供了一种有效的策略。图形概要
