Synthesis of hierarchical TS-1 with convenient separation and the application for the oxidative desulfurization of bulky and small reactants

Enhancement of Oxidative Desulfurization Performance over UiO‐66(Zr) by Titanium Ion Exchange

“…[5][6][7][8] Of those,s ome porousm aterials withT i active sites exhibited highly efficient catalysis in ODS reactions. [9][10][11][12] These studies indicated that richp orosity and large surfacea rea are beneficial fore nhancing the ODS activity of catalysts because their mass transfer ability can be improved. [13,14] Recently,m etal-organic frameworks (MOFs) have attracted considerable attentiond ue to their advantages such as high porosity, large surfacearea, and high thermal and chemical stability.…”

Deep oxidative desulfurization of dibenzothiophene using low-temperature-mediated titanium dioxide catalyst in ionic liquids

“…Moreover, the Ti-containing materials were pollution-free and cheap [22][23][24]. So far, a lot of attentions have been paid to titanium silicalite (TS), such as micro/mesoporous TS-1 [22], Ti-HMS [25] and hierarchical TS-1 [26]. In addition, titanium dioxide (TiO 2 ) has also been extensively investigated, and many researchers have paid attention to TiO 2 in nanotube morphology or as a carrier [27,28].…”

Microporous titania–silica nanocomposite catalyst-adsorbent for ultra-deep oxidative desulfurization

“…Therefore, many efforts have been devoted to prepare new crystalline Ti-containing silica molecular sieves with larger pore sizes, such as Ti-HMS [34], Ti-SBA-15 [35], Ti-SBA-16 [36], Ti-WMS [37], Ti-beta [38], Ti-MWW [39], as catalysts for the ODS of bulky sulfur compounds. However, these materials suffer from relatively low activities and/or poor stabilities [40]. On the other hand, it has been reported in the literature that amorphous mesoporous TiO 2 -SiO 2 mixed oxides are promising catalysts for reactions involving bulky reactants such as epoxidation of α-isophorone [41].…”
