Solids were characterized by several techniques. The phase ZSM-5 was obtained varying silica source and AlMCM-41 only can be obtained with TEOS. For this later phase, a hexagonal arrangement improved was observed at higher temperature and time of synthesis- Combines solids ZSM-5/AlMCM-41 only can be obtained from TEOS. X-ray patterns of combined solids indicated incipient formation of ZSM-5. Mesoporosity can be confirmed by N2 adsorption isotherms and TEM micrographs. %K Molecular sieves %K ZSM-5 %K AlMCM-41 %K Microporous solids %K Mesoporous solids. %U http://www.saber.ula.ve/bitstream/123456789/31546/1/ac5_5_2.pdf
