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 کاملZnFe2O4-TiO2 Nanoparticles within Mesoporous MCM-41
A novel nanocomposite ZnFe(2)O(4)-TiO(2)/MCM-41 (ZTM) was synthesized by a sol-gel method and characterized through X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), N(2) adsorption-desorption, Raman spectroscopy, and ultraviolet visible (UV-vis) spectrophotometry. The results confirmed the incorporation of ZnFe(2)O(4)-TiO(2) nanoparticles inside the pores of th...
متن کاملEffects of surface treatment of MCM-41
To apply mobile crystalline material 41 (MCM-41), which has a larger specific surface area than many other nanoporous silicas, for energy absorption, chlorotrimethylsilane treatment is performed to adjust the structure of inner surfaces of nanopores. As the treatment time is sufficiently long, the pore surface can be changed from hydrophilic to hydrophobic, leading to an energy absorption effic...
متن کاملCharacterisation of Molecules in MCM-41 Channels
The observation of molecular clusters has been of interest for some time. Molecular clusters can show quite different dynamic and static phase behaviour from bulk systems, and, because of their limited size, are accessible to computational molecular dynamics techniques.1-3 Experimentally, molecular clusters are made using several methods, including supersonic jets, vapours, confinement of phase...
