“…In the present study, SBA-15 was employed as a candidate catalyst for the ODH of isobutane. FSM-16, MCM-41, and SBA-15 are all examples of mesoporous silica based on a uniform hexagonal structure (Fukuoka et al, 2006;Hoffmann et al, 2006). However, the pore sizes of SBA-15 are greater than those of either FSM-16 or MCM-41 and can be controlled within a wider range (6-15 nm) by manipulating the interconnections between mesopores and micropores (Miyazawa and Inagaki, 2000;Zhao et al, 2006).…”

“…500-1000 m 2 g -1 ), which are attractive as catalysts and supports. However, the 75 understanding the role of mesoporous silica is generally limited to give higher dispersion of active sites than over the conventional silica. From the viewpoint of molecular level, the participation of mesoporous silica in the catalytic reactions is through the silanols (or hydroxyl groups) on the 80 surface.…”

“…75 The surface area and dispersion of Pt nanoparticles over mesoporous silica are higher than those of conventional SiO 2 -and Al 2 O 3 -90 supported catalysts (Table 1). conversion less than 30% under the same reaction conditions, and require 423 K or even higher temperature to remove majority of CO. 25 In particular, Pt(p)/FSM-16 gives ca.…”

“…One reason is probably due to the fact that noble metals, such as Pt, iridium (Ir), Pd, etc., have highly symmetric facecentered cubic (fcc) crystal structures, which will affect the growing progress of the crystals. Until now, various synthesis methods have been developed to grow Pd nanowires using either template-directed synthesis [11] or solution-phase techniques [12]. For instance, Nevin et al synthesized vertically grown Pd nanowire array using anodic aluminum oxide (AAO) template attached with silver epoxy to Ti foil as substrate [13].…”
