A novel anionic surfactant templating route for synthesizing mesoporous silica with unique structure

TL;DR: This work shows a templating route for preparing mesoporous silicas based on self-assembly of anionic surfactants and inorganic precursors and uses aminosilane or quaternized aminosILane as co-structure-directing agent (CSDA), which is different from previous pathways.
Journal ArticleDOI

Catalytic properties of hierarchical mesoporous zeolites templated with a mixture of small organic ammonium salts and mesoscale cationic polymers.

TL;DR: Mesoporous zeolites from nanosized carbon templates have been successfully synthesized, but their industrial applications are still limited by the complexity of the synthetic procedure involved and the hydrophobicity of the carbon templates.
Journal ArticleDOI

Periodic arrangement of silica nanospheres assisted by amino acids.

TL;DR: Uniform-sized silica nanospheres with a well-ordered arrangement were successfully synthesized by a novel and simple method using hydrolysis and condensation reactions of tetraethyl orthosilicate in the presence of basic amino acids.
Journal ArticleDOI

Adsorption of Chromate and Arsenate by Amino-Functionalized MCM-41 and SBA-1

TL;DR: In this paper, the authors report the characteristics of aminosilane-grafted mesoporous silicas as adsorbents of oxyanions in acidic conditions and examine the influence of amino group density.
Journal ArticleDOI

Superhydrophobic nanoporous polymers as efficient adsorbents for organic compounds

TL;DR: In this article, superhydrophobic nanoporous polydivinylbenzene materials are successfully synthesized by a novel solvothermal route, which exhibit high surface area, large pore volume, controllable average pore size, super-hydrophobicity and superoleophilicity.
