incorporation of [fe(bipy)cl4][bipy.h] (1) (where bipy is 2,2′-bipyridine) in the molecular sieves of the type lta, nay and mesoporous al-mcm-41 by using a “ship in a bottle synthesis” approach was investigated. [fe(bipy)cl4][bipy.h] was successfullyincorporated in the channels ofmesoporousal-mcm-41, and the product was characterized by x-ray diffraction, ftir and bet analysis. it was fou...

Ecofriendly chitosan/Al-MCM-48 (CH/Al-MCM) was synthesized from natural microcline and assessed as a potential adsorbent of As (V) ions with enhanced capacity. The adsorption properties CH/Al-MCM were in comparison Al-MCM-41 single phase. studied exhibits 178.6 mg/g capacity which is higher than (124 mg/g). illustrated based on the pseudo-first-order kinetic, Langmuir isotherm, monolayer model ...

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...

A meso-structured Al-MCM-41 material was impregnated with bromocresol green (BG) dye and then incorporated into a UV-Vis DRA spectroscopic instrument for the online detection of ammonia gas. The absorption response of the Al-MCM-41/BG ammonia sensing material was very sensitive at the optical absorption wavelength of 630 nm. A high linear correlation was achieved for ppmv and sub-ppmv levels of...

TiO2/Al-MCM-41 composites with various titania content were prepared by loading titania into the mesopores of Al-MCM-41 mesoporous molecular sieve from coal-measure kaolin as silicon and aluminum source via general sol-gel method and incipient wetness impregnation method. TiO2/Al-MCM-41 composites were characterized by XRD, FT-IR and SEM, and the photocatalytic degradation of methyl orange solu...
