A family of Fe-containing SBA-15 silica synthesized by a simple one-pot hydrothermal method was synthesized and tested in the hydrogen sulfide partial oxidation for sulfur production at 200°C and atmospheric pressure. All these materials maintain the porous hexagonal structure of SBA-15 showing a good chemical and mechanical stability. Isolated Fe 3+ species are mainly observed at high Si/Fe...
Vanadium oxide–containing mesoporous materials, based on a surfactant expanded zirconium phosphate with silica galleries into the interlayer space, named porous phosphate heterostructure (PPH), were prepared by using TEOS and vanadium oxytripropoxide in n-propanol as sources of Si and V, respectively; with different Si/V molar ratios of 1, 2, 5 and 25; and calcining at 550°C for 6h. Using this method,...
