A novel route is proposed for the preparation of mesopore containing zeolite ZSM-5 via in situ hydrothermal treatment of a solution containing alkali-dissolved SBA-15 containing carbonized surfactant P123 in the mesopores; it exhibited prominent stability enhancement for methanol to propylene reaction.

The successful in situ synthesis of metallophthalocyanines in mesoporous matrices is presented in this report. To overcome the high hydrophobicity of phthalocyanine (Pc) compounds in conventional wet chemical methods, a simple but effective route is developed to incorporate the metallophthalocyanines into the mesoporous matrix via an in situ reaction process between pre-loaded metal ions and 1,...

A novel type of material encapsulating phase-change materials (PCMs) is reported concerning their implication for use as thermal energy storage devices. The composites of siliceous SBA-15 or carbonaceous CMK-3 mesoporous assemblies and organic PCMs could be used to make leak-free devices that retain their capabilities over many thermal cycles for heat storage/release. A confinement effect was o...

Catalyst is the key for hydrodeoxygenation (HDO) of lignin derivatives to produce alkyl aromatics and cycloalkanes, components 100% sustainable aviation fuels (SAF). Mono bi-functional catalysts nickel (Ni) heterophosphotungstic acid (HPW) supported on SBA-15 carbons were prepared, characterized evaluated HDO derived trans-anethole. The structure was intact but its surface area pore volume decr...

In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiff-base compound (N,N´-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption–desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area a...

IR and NMR spectroscopy were used to determine the silanol content in the most common mesoporous ordered silicas: MCM-41, MCM-48, SBA-15 and SBA-16. In addition, a spray dried MCM-41 and an ethene bridged PMO are investigated. The results are compared with a commercial chromatographic silica (Nucleosil). The complete distribution of surface and bulk silanols, and of isolated, geminal and vicina...

in this work, bsea-sba-15 was prepared for the first time, which was prepared by covalently anchoring schiff-base compound (n,n´-bis(salicylidene)ethylenediamine (bsea) on sba-15 by hydrothermal method. the structure and physicochemical properties were determined by elemental analysis, xrd, nitrogen adsorption–desorption, thermogravimetric analysis and ftir spectroscopy, sem, bet surface area a...

Amino-functionalized SBA-15 mesoporous silica was prepared, characterized, and used as an adsorbent for heavy metal ions. The organic–inorganic hybrid material was obtained by a grafting procedure using SBA-15 silica with 3-aminopropyl-triethoxysilane and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272), respectively. The structure and physicochemical properties of the materials were cha...

Assessment of adsorption zinc (II) ions from aqueous solution using alginate-SBA-15 sorbent nanocomposite was investigated as a function of zinc concentration, solution pH, and contact time. For that purpose, the alginate-SBA-15 nanocomposite adsorbent was prepared through encapsulation method by immobilization mesoporous SBA-15 into a polymeric matrix. Identification of functional groups and s...
