钒掺杂的钛酸钠纳米管作为多相催化剂用于室温下硫化物的氧化

摘要

合成了一种含有TiO2, Na和V的多相纳米管催化剂,采用红外光谱、X射线衍射、扫描电镜、透射电镜和N2吸附-脱附法对该催化剂的结构和织构性质进行了表征,并用于水中30%H2O2选择性氧化硫化物制备对应的亚砜。该法具有产率极高、多相体系和简便等优点,可用于含一系列官能团底物的氧化,产物分离简便。%A heterogeneous titanate nanotube (TNT) catalyst containing TiO2, Na, and V has been synthesized and used in the chemoselective oxidation of sulfides to the corresponding sulfoxides in the presence of 30%H2O2 in water. Some of the advantages of our method include excellent yields, heterogene‐ous conditions, simplicity, compatibility with a variety of functionalities, and ease of isolation of the products. Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and N2 adsorption were used for structural and textural charac‐terization of the catalyst (VNaTNT).
