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 MCM-41 and Al-MCM-41 were synthesized using the molar composition: 1 Si02: 0.04 Al03: 0.24 CTAB: 0.3 Na2O: 150 H20. Through the thermal analysis it was possible to observe different peaks related to the presence of volatile materials and the structural director in the materials. Using techniques of characterization like XRD was possible to confirm the formation of the mesoporous structures using the amorphous silica derived from rice husk ash as a silica source.
