In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and its structural properties were characterized by nitrogen physisorption isotherms, transmission electron microscopy and Raman spectroscopy. According to BET and BJH methods, the specific surface area (SBET) and the average pore diameter of GMC are estimated to be 720 m2/g and 3.4 nm, respectively....

A carbon-based nanoporous sorbent was first used for microextraction in a packed syringe (MEPS) before HPLC/UV analysis of some biophenols in rat plasma. A laboratory-made programmable apparatus was designed and used for automation of the extraction procedure. The MEPS syringe was packed with 2 mg of CMK-3 sorbent, between the barrel and the injection needle, and mounted on an apparatus for pro...

This text reports the morphological and textural behavior of synthesis stages a CMK-3 carbon type using silicon matrix SBA-15 calcined at 823 K as template. During synthesis, three intermediate materials were obtained because (i) addition sucrose to template (CCMK3-1st), (ii) CCMK3-1st material (CCMK3-2nd), (iii) carbonization by pyrolysis by-product CCMK3-2nd (CCMK3-F). The texture above was f...

Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...

Abstract Porous carbon is well known as a good candidate for the development of electrochemical double-layer capacitors. Predominantly, many conventional carbons are microporous and often described by assumption slit pore geometry. However, there class that significantly different from others, namely templated mesoporous carbons. In this work, we study electrosorption-induced deformation in CMK...
