“…This assumes that the dspacing is closely related to the pore size. The relationship of the co-surfactant molecular weight to pore size is similar to that of Zhang [40] and Mou et al [41] who demonstrated the decrease in the pore diameter with the increase of the molar content of Itype ionic surfactants.…”

[22,23,26] As shown in Fig. 6(c) and (d), the 31 P MAS NMR spectra of both as-made and calcined CoAPO-34 contain intense spinning sidebands, indicative of a larger paramagnetic shift anisotropy rather than the negligible diamagnetic chemical shift anisotropy typically observed for tetrahedrally-coordinated P in AlPOs.…”

The cobalt-doped aluminophosphate molecular sieve, CoAPO-34 (with the chabazite-type topology) was prepared under ionothermal conditions using 1-ethyl-3-methylimidazolium bromide (EMIMBr) ionic liquid in presence of 1,6-hexanediamine (HDA). The HDA is not incorporated in CoAPO-34, but is required to mediate the availability of Co 2+ during the synthesis. The material was characterized using powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and solid-state NMR spectroscopy. Wideline 31 P NMR spectroscopy showed broad signals (~5000-10000 ppm wide), confirming that paramagnetic cobalt ions are successfully incorporated within the framework of the materials.

“…Platinum supported on alumina chlorine (Pt/Cl–Al 2 O 3 ) is the conventional industrial isomerization catalyst in the production of gasoline in petrochemical processes. However, the Pt/Cl–Al 2 O 3 catalyst can lead to corrosion and pollution and is sensitive to the addition of impurities such as water and sulfur compounds to feedstocks . The use of zeolites as an acidic support can eliminate such problems .…”

In this study, Y zeolite nanocrystals were synthesized without an organic template and were used as a support for bifunctional nanocatalysts in the hydroisomerization of n‐octane. Different types of catalysts were synthesized by loading Pt, Cr, and phosphomolybdic acid (HPMo) on Y zeolite nanocrystal supports and were characterized by X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET), field emission scanning electron microscope (FE‐SEM), and transmission electron microscope (TEM) analysis. The Cr‐Pt/HPMo‐Y nanocatalyst with a surface area of approx. 600 m2/g showed the best performance in the hydroisomerization of n‐octane. The optimization of n‐octane hydroisomerization over bifunctional nanocatalysts supported on nanocrystalline Y zeolite, in the presence of H2 gas, was applied based on the response surface methodology (RSM) and Box–Behnken design (BBD) template. The effect of three different process variables on the yield of iso‐alkanes as the purpose process was determined. Experiments were carried out using a fixed‐bed microreactor under different ranges of weight hourly space velocity (WHSV) (A = 0.5–1.5 hr−1), H2 to n‐C8 molar ratio (B = 1:1–3:1), and reaction temperature (C = 200–300°C). The RSM proved that the temperature variable had the greatest impact on the hydroisomerization reaction yield.
