Two-dimensional nanomaterials have received extensive attention because of their unique physicochemical properties. However, bottom-up synthesis of two-dimensional (2D) stable nanomaterials still remains great challenge. In this work, a novel 2D metal-organic (Cu-BDT) nanosheet is constructed at room temperature by coordinative self-assembly, namely, using monovalent copper ion as the metal precursor and 1,4-benzenedithiol as organic ligand. As-synthesized Cu-BDT nanosheets are fully characterized by various techniques including powder-diffraction of X-rays (P-XRD), Fourier transform infrared spectrometer (FT-IR), Raman spectra (Raman), scanning electron microscopy (SEM), transmission electron microscope (TEM), atomic force microscope (AFM), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectrometer (ICP-OES) and contact angle test. The catalytic result verifies that the Cu-BDT nanosheet surfaces possess abundant active sites and good hydrophobicity, which facilitate oxidation of sulfides into sulfoxide compounds.

二维疏水铜基纳米片的合成及其在硫化物催化氧化中的应用

二维纳米材料因其独特的理化性质而受到广泛关注。然而，二维（2D）稳定纳米材料的自下而上合成仍然是一个巨大的挑战。在这项工作中，通过配位自组装在室温下构建了一种新型的二维金属有机 (Cu-BDT) 纳米片，即使用一价铜离子作为金属前驱体和 1,4-苯二硫醇作为有机配体。合成后的 Cu-BDT 纳米片可通过各种技术进行充分表征，包括 X 射线粉末衍射 (P-XRD)、傅里叶变换红外光谱仪 (FT-IR)、拉曼光谱 (Raman)、扫描电子显微镜 (SEM)、透射电子显微镜（TEM）、原子力显微镜（AFM）、X射线光电子能谱（XPS）、电感耦合等离子体发射光谱仪 (ICP-OES) 和接触角测试。催化结果验证了Cu-BDT纳米片表面具有丰富的活性位点和良好的疏水性，有利于硫化物氧化成亚砜化合物。
