近几十年来，柴油氧化脱硫（ODS）技术因满足日益严格的标准而备受关注，但氧化剂利用率低仍是一个巨大的挑战。采用一步水热法制备了含铁钛纳米管（Fe-TiNTs），并在此基础上实现了高脱硫率和最低的n（H2 O2）/n（S）。采用X射线衍射（XRD）、扫描电镜（SEM）、透射电镜（TEM）、N2吸附-脱附等手段对催化剂进行了表征。对于DBT，硫去除率接近99%，Fe-TiNTs在ODS中显示出优异的催化选择性，并且它们的活性在各种柴油化合物的存在下不会显著降低。表征和碘量滴定分析表明，该催化剂的高活性与Ti-η1-过氧化氢和自由基氧化机理有关。
Oxidative desulfurization (ODS) in diesel has attracted great attention for meeting the increasingly stringent standards in last few decades but remains a huge challenge that oxidant is underutilization. We achieve the high sulphur removal and the lowest n(H2O2)/n(S) over a smart heterogeneous catalyst of Fe-containing Ti-nanotube (Fe-TiNTs) which was prepared and synthesized by one-step hydrothermal method. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption–desorption and so on were used to characterize the catalyst. For DBT, the sulphur removal rate was nearly 99%, the Fe-TiNTs showed excellent catalytic selectivity in ODS, and their activity does not decrease significantly in the presence of various diesel compounds. The characterizations and iodometric titration analyses show that the high activity is related to the mechanism of Ti-η1-hydroperoxide and radical oxidation.Graphical Abstract
