Application of sodium titanate nanotubes doped with vanadium (VNaTNT) as a heterogeneous catalyst for oxidation of sulfides at room temperature

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, heterogeneous 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 characterization of the catalyst (VNaTNT).

Graphical AbstractSodium titanate nanotube doped with vanadium (VNaTNT) has been synthesized, and it showed excellent catalytic performance for the chemoselective oxidation of sulfides in the presence of 30% H2O2 in water. FT-IR, XRD, SEM-EDX, TEM, TG, BET and DRUV were used for characterization of the VNaTNT.Figure optionsDownload full-size imageDownload as PowerPoint slide
