The template ion exchange of chromium cations into FSM-16 (#16 Folded Sheets Mesoporous Materials) for 247 h resulted in a 2.89 wt % incorporation of those cations into the FSM-16, although only a 0.3 wt % incorporation had previously been reported. The XRD pattern of the resultant solid (Cr-FSM-16) showed that the hexagonal structure characteristic of FSM-16 remained after the 2.89 wt % incorporation of chromium cations. XPS could be used to detect the Cr 3+ and Cr 6+ species on the surface of Cr-FSM-16. A pre-edge peak that was due to a tetrahedrally coordinated Cr 6+ species was confirmed in the XANES spectrum of the Cr-FSM-16, which showed that the coordination state around some Cr species was similar to that around the Si species in FSM-16. With the increase in the amount of chromium cations in FSM-16, its catalytic activity and stability during the oxidative dehydrogenation of isobutane were evidently improved.

“…This work CH 2 -CH-CH 2 OH OH OH Dehydration and hydrogenation from the previous study ( Sugiyama et al, 2013b), the activities using W-FSM-16 were greater and more stable than those using P-FSM-16. MCM-41 also showed stable activity for the conversion of 1,2-PD, while both the selectivity to and the yield of PA were lower than the values obtained using W-FSM-16.…”

“…Therefore, the catalytic conversion of 1,2-PD to PA is one of the most likely uses of glycerol. In our previous paper (Sugiyama et al, 2013b), the conversion of 1,2-PD to PA effectively proceeded with FSM-16, particularly when molded by wet treatment rather than by typical pressurization.…”

“…Glycerol can be favorably converted to 1,2-propandiol (1,2-PD) via dehydration to hydroxyacetone, followed by hydrogenation to the diol (Figure 1) (Chiu et al, 2008;Huang et al, 2008;Sato et al, 2009). In a previous paper, we reported that the conversion of 1,2-PD to propanal (PA) effectively proceeded with FSM-16 (#16 folded sheets of mesoporous materials) ( Figure 1) (Sugiyama et al, 2013b). FSM-16 was first prepared in 1993 (Inagaki et al, 1993).…”

We have earlier showed how the catalytic conversion of 1,2-propandiol to propanal using FSM-16 (#16 folded sheets of mesoporous materials) when molded by wet treatment proceeded more favorably than when using FSM-16 molded by pressurization, while no comparison using other typical acidic catalysts and no examination of the acidic properties of FSM-16 was carried out. In the present study, the conversion using FSM-16 molded by wet treatment and pressurization was compared with that obtained by using typical acidic catalysts such as SiW12O40/SiO2 and MCM-41 (#41 of Mobil Composition of Matter) together with amorphous SiO2. Among these catalysts, FSM-16 molded by wet treatment showed the most suitable catalytic activity. In order to examine the effect of the molding procedure for FSM-16 on its structural and acidic properties, FSM-16 molded by both methods was examined using NH3-TPD, in situ FT-IR using NH3 as a probe molecule, and Hammett indicators together with XRD and TEM. According to Zaitsev's rule, the present conversion should afford acetone rather than propanal, which indicates that it would proceed via hydro cracking. Therefore, the conversion of 1,2-propandiol using FSM-16 was also examined in the presence and absence of hydrogen. Furthermore, hydration reactions of 1-and 2-propanol when using FMS-16 were examined. Based on the results obtained from this investigation, it was concluded that the conversion using a more acidic FSM-16 molded by wet treatment proceeded through dehydration rather than through hydro cracking.

Although previous researchers have found that FSM-16 (#16 Folded Sheet Mesoporous material) doped with chromium and related Cr-doped silica catalysts has shown great activity for the oxidative dehydrogenation of isobutane to isobutene, information on the nature of these catalysts is insufficient. For this study, three types of Crdoped silica catalysts were prepared by applying the template ion exchange method. CrOx/FSM-16 and CrOx/SiO 2 were used as references. These catalysts were used for oxidative dehydrogenation, which was then characterized via various techniques. The most active catalyst was Cr-doped silica, which did not have the hexagonal structure that is characteristic of mesoporous FSM-16. Various characterizations showed that the catalytic activity of the Cr-species, stemmed from a weak acidic nature and a redox nature that originated from the combination of silicate and a Cr cation, as opposed to the hexagonal structure and strong acidic nature of FSM-16.
