Resumen
Research, synthesis and catalytic application of molecular sieves areas has been constituting a large field of development and prominence in recent decades, due to the large potential of these materials in respect of theirs catalytic properties. The need for costs reduction in the production of these structures, has encouraged the search for new sources of reactants which could provide an equal application of these sieves together with low costs. This work has the aim to obtain and to characterize molecular sieves type MCM-41 and Al-MCM-41 using new routes of synthesis. The molecular sieves MC

Resumen
In this paper, mesoporous MCM-41 and Al-MCM-41(Si/Al =100, 70, 40, 10, 5) molecular sieves were synthesized by direct hydrothermal process and characterized by various analytical techniques. Their catalytic performance in the synthesis of dioctyl phthalate (DOP) was also studied. The results show that while keeping the mesostructure of Al-MCM-41(Si/Al=100, 70, 40), increasing Al content can increase the acidity and so forth effectively improve the catalytic activity. But too much aluminum incorporation can destroy the structure of Al-MCM-41(Si/Al=10). The Al-MCM-41 molecular sieves with proper

M-MCM-41 (M = Al, Cu, Cr, Ti) were synthesized by hydrothermal method and characterized by XRD. Rhodamine B molecules were encapsulated into these mesoporous molecular sieves by impregnation method. Steady fluorescence measurements indicated that doping of Al ions into MCM-41 enhanced largely the fluorescence intensities, but more Al decreased the fluorescence intensities resulting from the formation of Al2O3.

Al-containing mesoporous molecular sieves(Al-MCM-41) were synthesized at ambient temperature. The structures of samples were characterized by XRD, N2-adsorption/desorption isotherms and FT-IR, etc. The evaluation results showed that Al-MCM-41 had higher catalytic activity for isomerization conversion of endo-tetrahydrodicyclo-pentadiene (endo-TCD) into exo-tetrahydrodicyclo-pentadiene (exo-TCD) and adamantane (AdH). Loading inorganic acid on the surface of Al-MCM-41 led increase of its catalytic activity and the yield of adamantane.

A new procedure for synthesis of MCM-41 siliceous molecular sieves with regular morphologies and bimodal mesoporous silica was developed. It is based on the precipitation from an isotropic reaction mixture. The decrease in pH, which causes the formation of solid particles, is achieved by the hydrolysis of ethyl acetate. The procedure is excellently reproducible and enables to obtain not only siliceous MCM-41 with the highest degree of pore ordering and phase purity but also a material of a new type, viz. bimodal silica containing both the MCM-41 mesopore system and the system of larger mesopor
