in this paper, the possibility of using a new ordered nanoporous carbon as a new fiber in headspace solid phase microextraction (hs-spme) to determine of mononitrotoluenes (mnts) in waste water is demonstrated. the structural order and textural properties of the ordered nanoporous carbon were studied by x ray diffraction (xrd), scanning electron microscopy (sem) images and nitrogen adsorption i...

Ordered nanoporous silicas containing various binary copper-manganese oxides were prepared as catalytic systems for effective carbon monoxide elimination. The carbon monoxide elimination efficiency was demonstrated as a function of the [Mn]/[Cu] ratio and reaction time. The prepared catalysts were characterized by Brunauer-Emmett-Teller (BET) method, small- and wide-angle X-ray diffraction (XRD...

We report a simple and direct synthetic method for the preparation of nanoporous carbon nanotubes with larger pores (>10 nm) on the tube wall. The method combines the use of anodic aluminum oxide (AAO) as a template for the tube diameter and block copolymer/carbohydrates self-assembly within thin films confined inside AAO pore channels to form nanopores. It involves coating the AAO inner pore c...

Nanostructured carbon materials, including carbon nanotubes, membranes, and particles, are an important nanomaterial for many applications in nanoelectronics, sorption and separation, sensors, catalysis, and energy conversion and storage (e.g., double layer capacitors, and hydrogen storage). Varied methods have been developed to synthesize nanostructured carbon materials, such as DC arc-dischar...

Poly(alkylene oxide)-type block copolymers have been recently shown to be particularly versatile as structure-directing agents for the preparation of ordered large-pore mesoporous silica materials. In principle, the structure direction is achieved through the formation of periodic supramolecular self-assemblies between the polymeric surfactants and a silica source in the aqueous solution. The o...

In the present work, well ordered, mesoporous carbon nitride (MCN) sorbent with uniform mesoporous wall, high surface area and pore volume has been fabricated using the simple polymerization reaction between ethylene diamine and carbon tetrachloride in mesoporous silica media, and then modified by TiO2 nanoparticles (Ti-MCN). The structural order and textural properties of the nanoporous materi...

Nanoporous Au-Fe alloy was synthesized via a wet chemistry route using ordered nanoporous silica as a hard template. The nanoporous Au-Fe consisted of aligned arrays of nanopores that were uniform in composition and ordered in hexagonal lattice, whereas Au-Fe nanoparticles synthesized without templates exhibited broad dispersions in the chemical composition and/or particle size. Nanoporous Au-F...

Ordered mesoporous carbons with various structures, designated as CMK-1~5, have been synthesized by carbonization of sucrose, furfuryl alcohol or other suitable carbon sources inside silica or aluminosilicate mesopores that are interconnected into three-dimensional networks such as in MCM-48 (cubic Ia3d), SBA-1 (cubic Pm3n) and SBA-15 (hexagonal p6mm). The mesoporous carbon molecular sieves, ob...
