Hydrothermally Stable Periodic Mesoporous Ethane-Silica and Bimodal Mesoporous Nanostructures
Journal of Nanoscience and Nanotechnology, 2011We report the hydrothermally stable organized periodic mesoporous organosilicas (PMOs) and bimodal mesoporous structures by using mixed templates of oligomeric alkyl-ethylene oxide and ionic surfactants under basic conditions. Oligomeric alkyl-ethylene oxide surfactant [(Polyoxyethylene (2) cetyl ether, structure is C16H33(OCH2CH2)nOH, n-2, hereafter ...

Preparation of Mesoporous SiCBN Ceramic Templated by Mesoporous Carbon
Journal of the Korean Ceramic Society, 2007Well-ordered mesoporous SiCBN ceramics have been successfully synthesized by infiltrating a polymeric precursor, which was prepared from borazine and 2,4,6-trimethyl-2,4,6-trivinylcyclotrisilazane via a hydroboration reaction, into a mesoporous carbon (CMK-3) as a hard template.

Periodic mesoporous hybrid monolith with hierarchical macro–mesopores
Microporous and Mesoporous Materials, 2007Abstract We describe the synthesis of hybrid monolith with hierarchically macro–mesoporous structure by a sol–gel process from the mixture of 1,4-bis(triethoxysilyl)benzene (BTEB) and tetraethoxysilane (TEOS) using poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (P123) as structure directing agent under acid medium.

Mesoporous Calcite by Polymer Templating
Crystal Growth & Design, 2008Layered calcite crystals with internal 10−50 nm pores are precipitated from aqueous solution containing a polymer−peptide conjugate that aggregates into pore-forming templates. The zwitterionic peptide sequence behaves as the “binding block” of a double-hydrophilic block copolymer, facilitating templating, nucleation inhibition, and stabilization of ...

Mesoporous Metallic Iridium Nanosheets
Journal of the American Chemical Society, 2018Two-dimensional (2D) metals are an emerging class of nanostructures that have attracted enormous research interest due to their unusual electronic and thermal transport properties. Adding mesopores in the plane of ultrathin 2D metals is the next big step in manipulating these structures because increasing their surface area improves the utilization of ...

Alumina with a fairly large surface area (415 m2g−1) and narrow pore size distribution (pore diameter ∼3 nm), containing octahedral and tetrahedral aluminum, prepared by long chain neutral amine as the surfactant, shows some evidence of textured structure.

Assemblies of Biomaterials in Mesoporous Media
Journal of Nanoscience and Nanotechnology, 2006Assemblies of biomaterials onto mechanically stable inorganic structure are advantageous for the practical applications because of the potential to improve the stability and performance of biomaterials in the biocatalytic processes. Among many kinds of inorganic materials, mesoporous materials such as mesoporous silica and mesoporous carbon have ...
