Perspectives in catalytic applications of mesostructured materials

Multiscale modeling of transport and residence times in nanostructured membranes

“…Mesoporous materials, which find widespread application in catalysis, 1,2 are typically used in powder or pellet form, such as in a packed-bed reactor. Robust mesoporous membrane reactors could find interesting applications and might have some advantages over pellets.…”

High Selective Oxidation of Alcohols Based on Trivalent Ion (Cr3+and Co3+) Complexes Anchored on MCM-41 as Heterogeneous Catalysts

“…The high concentration of silanol groups is suitable for the immobilization of metal complexes. 4 Up to now, various immobilization methods have been reported to prepare the heterogenized complexes. The one used frequently was to immobilize the active groups onto support through coordination of metal ion to the terminal functional group of a surface-bound linker.…”

Application of Sulfonic Acid Functionalized Nanoporous Silica (SBA-Pr-SO3H) for One-Pot Synthesis of Quinoxaline Derivatives

“…They can be used as catalysts (Trong On et al 2001, Mohammadi et al 2007, for the preconcentration of metals (Ganjali et al , 2004, and as modified carbon electrodes (Badiei et al 2005, Zhang et al 2006, Walcarius et al 1999. The SBA-15 is new nanoporous silica with hexagonal structure, large pore, high surface area, high thermal stability and also diffusion free due to thicker pore walls and larger pore 1 H NMR (250 MHz) was run on a Bruker DPX, 250 MHz.…”
