چکیده
in this work, we report a new well dispersed molybdenum complex attached through the mediation of aminopropylsilyl groups on the surface of multi-walled carbon nanotubes (mwcnts). the prepared hybrid nanomaterial was characterized with different physicochemical methods such as fourier transform infrared and atomic absorption spectroscopies, transmission electron microscopy, energy-dispersive x-ray and nitrogen adsorption-desorption analyses. nitrogen adsorption-desorption analysis revealed that the textural characteristics of the support were preserved during the grafting experiments despite sequential reduction in surface area. elemental analysis showed the presence of 0.1 mmol molybdenum per gram of the catalyst. the prepared hybrid nanomaterial showed good performance and stability in the catalytic epoxidation of olefins under mild reaction conditions.

متن کاملNew Hybrid Nanomaterial Derived from Immobilization of 4-Formyl Benzo-9-Crown-3 Ether onto the Mesopores of MCM-41
In this work, we report a new hybrid nanomaterial based on the immobilization of 4-formyl benzo-9-crown-3 ether (FB9C3) onto the mesopores of MCM-41. First, the mesoporous molecular sieve MCM-41 was covalently grafted with 3-aminopropyl triethoxysilane to give aminopropyl modified MCM-41 (AmpMCM-41). Reaction of this material with FB9C3 afforded the B9C3-AmpMCM-41 hybrid nanomaterial. The prepa...
متن کاملAdsorption of Humic Acid On Multi-Walled Carbon Nanotubes
Background: Natural organic matters (NOMs) have the main role in formation of trihalomethanes. These compounds are in natural water sources due to biological activities. In the presented study, adsorption and separation of humic acid as an index of natural organic matters using multi-walled carbon nanotubes is evaluated. Methods: The experiments were carried out in bath adsorption reactors wit...
متن کاملApplication of Multi-Walled Carbon Nanotubes in the Removal of Reactive Red 120 from Aqueous Solutions
Background and purpose: Textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. Strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. In the present study, multi-walled carbon nanotubes (MWCNTs) were used as an adsorbent for the removal of Reactive Red-120 (...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولSimple immobilization of pyrroloquinoline quinone on few-walled carbon nanotubes
Pyrroloquinoline quinone (PQQ) was immobilized on glassy-carbon electrodes (GCE) modified with single-walled carbon nanotubes (SWCNT), few-walled carbon nanotubes (FWCNT) and carbon black (Vulcan XC72R). Modified electrodes were prepared by drop-casting. Immobilization was achieved with an extremely simple dipping procedure and without any further modification to the electrodes. Electrochemical...
