Vanadium oxide supported on mesocellulous silica foams (MCF): An efficient and reusable catalyst for selective oxidation of sulfides
A green, efficient and selective approach for the oxidation of sulfides to sulfoxides and sulfones with UHP at room temperature is reported. The reaction is performed in the presence of vanadia catalyst supported on mesocellular silica foam (MCF) with a V content ranging from 2% to 10% as heterogeneous and reusable catalyst. The structural and textural characterization of this catalyst were don...
متن کاملPartial Oxidation of Methanol over Highly Dispersed Vanadia Supported on Silica SBA-15
The partial oxidation of methanol to formaldehyde was studied over highly dispersed vanadia supported on mesoporous silica SBA-15 (VOx/SBA-15). VOx/SBA-15 catalysts were prepared by a novel grafting/ion-exchange method and characterized using UV-VISand Raman spectroscopy. The resulting surface vanadium oxide species (0 – 2.3 V/nm), grafted on the inner pores of the SBA-15 silica matrix, consist...
متن کاملOxidation of sulfur dioxide over supported vanadia catalysts: molecular structure ± reactivity relationships and reaction kinetics
The oxidation of sulfur dioxide to sulfur trioxide over supported vanadium oxide catalysts occurs as both a primary and secondary reaction in many industrial processes, e.g., the manufacture of sulfuric acid, the selective catalytic reduction of NOx with ammonia and the regeneration of petroleum re®nery cracking catalysts. This paper discusses the fundamental information currently available con...
متن کاملCyclohexene photo-oxidation over vanadia catalyst analyzed by time resolved ATR-FT-IR spectroscopy.
Vanadia was incorporated in the 3-D mesoporous material TUD-1 with a loading of 2% w/w vanadia. The performance in the selective photo-oxidation of liquid cyclohexene was investigated using ATR-FT-IR spectroscopy. Under continuous illumination at 458 nm a significant amount of product, i.e. cyclohexenone, was identified. This demonstrates for the first time that hydroxylated vanadia centers in ...
متن کامل1 Effect of the Chemical Composition of Mesoporous 2 Cerium - Zirconium Oxides on the Modification with 3 Sulfur and Gold Species and Their Application in 4 Glycerol Oxidation 5
Ceria, zirconia and mixed cerium-zirconium mesoporous oxides were synthesized and 12 used as supports for sulfur and gold species. The materials were characterised using selected 13 advanced techniques (ICP-OES, elemental analysis, XPS, XRD, N2 adsorption and desorption 14 isotherms, UV-vis, ATR-FTIR, TPR-H2, TG-DTA) which allowed monitoring of the oxidation state 15 of metals (cerium and gold)...
