Abstract: "The design of porous solid materials with size, distribution and morphology controlled and ordered pores has a scientific and technological interest, in addition to their potential application in the fields of electronics, photonics, catalysis, separation and filtration; where in the ceramic have excellent potential in many applications due to their of well known thermal and chemical stability. Di?erent processes have been developed for the synthesis of porous structures, of which sol-gel has been the most used. The generation of porous structures arranged in two and three dimensions ranging from the nanometer range up to the micrometer is induced by adding templantes agents (micelles, vesicles, liposomes or copolymers), which are subsequently removed by a thermal or chemical process. This research presents a review of sol-gel process emulsion which employs a precursor of silicon alkoxide (TEOS), where various reaction parameters influence their formation, as concentrations of the catalyst and water as well as the type material is performed and amount of solvent, reaction temperature and pH."
