An investigate of the stability of the composition tartrate stabilize the nano-porous of mesoporous composition

MCM-41 has a hexagonal arrangement of one-dimensional mesopores with diameters ranging from 2 to 10 nm [1]. The homogeneity of the pores, high surface area, and good thermal stability, which make them an attractive molecular sieve for applications in catalysis, sorption of large organic molecules, chromatographic separations, as well as host for quantum confinement of guest molecules [2-3].In this work, Mesoporous materials (MCM-41) wereprepared. Then, MCM-41coated with 3-aminopropyltriethoxysilane (APTES).yllaiiF,tartratewasimmobilized on thesemesoporousmaterial. The structural, morphological of prepared material were characterization by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, scanning electron microscopy/energy dispersive x-ray analysis (SEM-EDAX) and thermal gravimetric analysis (TGA).We demonstrate that the tartrate is attached to the mesoporoussurface, that the binding of tartrate to the mesoporous was confirmed by FT-IR analysis. The result of XRD analysis confirmed the mesoporous structure of the resulted material. SEM analysis indicated the relatively uniform particles. The thermal stability of the MCM-41 and the tartrate immobilized MCM-41was evaluated by TGA. TGA analysis indicated the enhanced thermal stability of tartrate immobilized MCM-41 is attributed to its cross-linked nature, since it is well-known that cross-linking leads to increased thermal stability.
