Pore Size Analysis of MCM-41 Type Adsorbents by Means of Nitrogen and Argon Adsorption.
Methods of nonlocal density functional theory (NLDFT), proposed recently for predictions of adsorption equilibrium and calculations of pore size distributions in micro- and mesoporous materials, were tested on reference MCM-41 materials. Five newly synthesized MCM-41 adsorbents with presumably uniform pore channels varying from 32 to 45 Å were characterized by X-ray diffraction (XRD), nitrogen ...
متن کاملEvaluation of Vapor Deposition Techniques for Membrane Pore Size Modification
The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...
متن کاملLysine-Grafted MCM-41 Silica as an Antibacterial Biomaterial
This paper proposes a facile strategy for the zwitterionization of bioceramics that is based on the direct incorporation of l-lysine amino acid via the ε-amino group onto mesoporous MCM-41 materials. Fourier transform infrared (FTIR) studies of lysine-grafted MCM-41 (MCM-LYS) simultaneously showed bands at 3080 and 1540 cm-1 and bands at 1625 and 1415 cm-1 corresponding to -NH3+/COO- pairs, whi...
متن کاملSynthesis Characterization and Catalytic Evaluation of Mesoporous Fe-MCM-41 and Si-MCM-41 Materials
Environmental concern associated with safe handling disposal of corrosive mineral acids such as HF have encouraged the development of safer and non waste producing alternative for application in catalysis. In this sense ,mesoporous materials attracted much attention of catalysis to transform big molecules into its useful products. In the present study we have synthesized, mesoporous Fe-MCM-41an...
متن کاملStudying Performance of Dubinin-astakhov and Dubinin-raduchkevic Equations to Evaluate Nanopore Volume and Pore Size of MCM-41 Particles (TECHNICAL NOTE)
MCM-41 particles were synthesized using inorganic raw materials and Cetyltrimethylammonium bromide (CTAB). The textural properties and structure of MCM-41 particles were characterized by XRD, SEM, TEM and N2 adsorption-desorption methods. To study performance of Dubinin-Astakhov and Dubinin-Raduchkevic isotherm models in evaluating mesopore volume and pore size of MCM-41 samples, the mesopore ...
