So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Arfaoui, Jihene; Ghorbel, Abdelhamid; Petitto, Carolina; Delahay, Gerard researched the compound: Bis(acetylacetonato)dioxomolybdenum(VI)( cas:17524-05-9 ).Safety of Bis(acetylacetonato)dioxomolybdenum(VI).They published the article 《A new V2O5-MoO3-TiO2-SO42- nanostructured aerogel catalyst for diesel DeNOx technology》 about this compound( cas:17524-05-9 ) in New Journal of Chemistry. Keywords: vanadium oxide molybdenum titanium sulfur nanostructured; selective catalytic reduction aerogel catalyst diesel nitrogen oxygen technol. We’ll tell you more about this compound (cas:17524-05-9).
A new V2O5-MoO3-TiO2-SO42- nanostructured aerogel system, containing V and Mo loadings representative of the V2O5-MoO3/TiO2 com. SCR catalyst, was developed via a one step sol-gel method combined with the supercritical drying approach for the low temperature selective catalytic reduction of NO by NH3, in excess O2. The new V2O5-MoO3-TiO2-SO42- catalyst was analyzed via x-ray diffraction, N2-physisorption, H2-TPR, NH3-TPD, Raman spectroscopy, XPS and DR UV-vis spectroscopy. The elaboration and characterization of TiO2, V2O5-TiO2, MoO3-TiO2, V2O5-MoO3-TiO2, TiO2-SO42-, V2O5-TiO2-SO42- and MoO3-TiO2-SO42- aerogel samples were also reported in this work. The results prove the successful synthesis of nanostructured aerogel materials with good crystallinity of the TiO2 anatase phase, a developed mesoporous texture and a nanometer size as new SCR catalysts. V, Mo and SO42- were highly dispersed on the TiO2 surface, and their presence and the diverse interactions developed between them strongly affect the physicochem. properties and catalytic behavior of the derived sol-gel powders. Among all the samples investigated, the new V2O5-MoO3-TiO2-SO42- aerogel was the most efficient catalyst for the low temperature NO-SCR: compared to a V2O5-WO3/TiO2 com. catalyst (EUROCAT), it demonstrates similar SCR activity in the 200-375° temperature range, but, at higher temperatures (375-500°), it exhibits superior catalytic performance. A complete conversion of NO into N2 (100%) was achieved in the 450-500° temperature range over the new V2O5-MoO3-TiO2-SO42- nanostructured aerogel catalyst, when the NH3-SCR reaction was realized using 1000 ppm NO and 1000 ppm NH3, in the presence of 3.5% H2O.
