Catalytic degradation of polyethylene over SBA-16

Korean Journal of Chemical Engineering, 2010
The performance of SBA-16 catalysts toward the degradation of two kinds of polyethylenes, high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), was evaluated by using a thermogravimetric ana- lyzer and batch reactor. The effect of the acidity of SBA-16 upon degradation efficiency was investigated.

Adsorption of carbon dioxide on organically functionalized SBA-16

Microporous and Mesoporous Materials, 2008
Abstract The adsorption of CO 2 on SBA-16 functionalized with N -(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPS) was investigated by DSC–TGA at 333 K. Hydrolysis of the calcined SBA-16 improved the adsorption performance. The functionalized samples prepared with hydrolyzed supports showed superior adsorption capacity and rate to those prepared

Microwave synthesis of cubic mesoporous silica SBA-16

Microporous and Mesoporous Materials, 2004
Cubic mesoporous silica SBA-16 materials with a rhombdodecahedral or decaoctahedral shape were synthesized by microwave reactions within 2 h using sodium silicate as the silica source and a triblock copolymer F127 as structure directing agents. The synthesis parameters, stirring time of the precursor solution before microwave reaction, microwave ...

Capillary Condensation of Nitrogen in MCM-48 and SBA-16

The Journal of Physical Chemistry B, 2003
To examine the effects of connectivity among pores of almost the same size and of different size and geometry on adsorption hysteresis and pore criticality, we measured the temperature dependence of the adsorption−desorption isotherm of nitrogen onto MCM-48 and SBA-16 materials, respectively, with well-defined three-dimensional networks of cylindrical ...

Optimization study of nanoporous cubic Ti-SBA-16

Journal of Porous Materials, 2017
The present study investigates the direct one step hydrothermal synthesis of three-dimensional (3D) Ti-SBA-16 (cubic, Im3m) by optimizing with ammonium fluoride (F/Si ratio ≤0.05), hydrothermal heating (40–130 °C) and aging time (24–120 h). The effective 3D mesoordering through silica condensation, in less acidic environment, co-solvent n-butanol and ...

Ordered mesostructured carbon templated by SBA-16 silica

Carbon, 2005
A novel synthesis of ordered cubic mesoporous carbon with an Im3m symmetry by using SBA-16 silica as a hard template was performed. SBA-16 was synthesized using pluronic F 127 as the structure-directing agent and tetra- ethylorthosilicate as the silica source.

Functionalization of SBA-16 silica particles for ibuprofen delivery

Journal of Sol-Gel Science and Technology, 2015
In this study, the surface of the hydrothermally synthesized SBA-16 was modified with 3-aminopropyltriethoxysilane (APTES) as a controlled drug delivery system. In this case, ibuprofen was chosen as a drug. Furthermore, it was loaded into the SBA-16 base and functionalized SBA-16.
