CuO nanoparticles encapsulated inside Al-MCM-41 mesoporous materials via direct synthetic route
Highly ordered aluminum-containing mesoporous silica (Al-MCM-41) was prepared using attapulgite clay mineral as a Si and Al source. Mesoporous complexes embedded with CuO nanoparticles were subsequently prepared using various copper sources and different copper loadings in a direct synthetic route. The resulting CuO/Al-MCM-41 composite possessed p6mm hexagonally symmetry, well-developed mesopor...
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 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 کاملRemarkable acceleration of cyanosilylation by the mesoporous Al-MCM-41 catalyst.
The presence of the heterogeneous mesoporous Al-MCM-41 catalyst remarkably accelerated the cyanosilylation of various aldehydes and ketones with trialkylsilyl cyanide, giving the corresponding cyanohydrin silyl ethers in quantitative yields under mild reaction conditions.
متن کاملFluoride ion sensing in aqueous medium by employing nitrobenzoxadiazole-postgrafted mesoporous silica nanoparticles (MCM-41).
A mesoporous silica-based inorganic-organic hybrid material (NBD-AP-MCM) has been designed and developed as a fluorescent chemosensor for the detection of fluoride in aqueous medium. The system was developed by covalently anchoring 7-nitro-2,1,3-benzoxadiazole (NBD) dye onto the surface of mesoporous silica nanoparticles, MCM-41. The system was characterized using several conventional analytica...
