Phenylthiourea Modified Highly Ordered Nanoporous Silica for Heavy Metal Ion (Hg2+ ) Trapping
The phenylthiourea-substituted triethoxysilane as a silane agent was synthesized and grafted on highly ordered nanoporous silica (LUS- 1) with a textured morphology and hexagonal array. This material (Tu-LUS-1) contained 0.8 mmol/g of soft base phenylthiourea group and surface area 760 m2 g-1 and was able to adsorb 0.75 mmolHg/g of TU-LUS-1 in endothermic reaction.
متن کاملInvestigation of Carbon Dioxide Adsorption on Amino-Functionalized Mesoporous Silica
Carbon dioxide (CO2) adsorption on unfunctionalized and amino-functionalized SBA-3 materials are investigated and compared in this study. The synthesized materials are characterized by various techniques such as X-ray diffraction (XRD), Brunauer-Emmet-Teller (BET) method, Fourier transform infrared (FT-IR) and Scanning electron microscopy (SEM).The isotherms of these materials have been measure...
متن کاملSingle-pot synthesis of ordered mesoporous silica films with unique controllable morphology.
Mesoporous silica films consisting of a monolayer of separated SBA-15 particles with unusually wide and short pores grown on silicon wafers have been fabricated in a simple single-pot-synthesis, and the formation of the films has been studied. A recipe for synthesizing mesoporous silica rods with the addition of heptane and NH4F at low temperature was used and substrates were added to the synth...
متن کاملFacile synthesis of highly ordered mesoporous silver using cubic mesoporous silica template with controlled surface hydrophobicityw
Recently, there has been great interest in the synthesis and application of various kinds of nanostructured noble metals such as platinum, gold and silver. Nanostructured silvers have been widely investigated as antimicrobial materials, bio-sensors, catalysts, and advanced materials exhibiting surface plasmon resonance and surface enhanced Raman scattering. All this research is mainly based on ...
متن کاملFacile synthesis of highly ordered mesoporous silver using cubic mesoporous silica template with controlled surface hydrophobicity.
Highly ordered mesoporous silver, which exhibits well-defined mesopores, high surface area and pore volume, has been successfully obtained using a cubic mesoporous silica, KIT-6, with controlled surface hydrophobicity as the hard template.
