PENA, JUAN; CARDONA, ELIANA  and  RIOS, LUIS. SYNTHESIS OF SILICON OXIDE WITH HIGH SUPERFICIAL AREA AND POROSITY THROUGH SOL-GEL TECHNIQUE USING GLYCEROL AND GLYCERYL MONOSTEARATE AS TEMPLATES. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.207-216. ISSN 0012-7353.

This paper reports a novel synthetic route for the production of porous silicon oxides (silica) by means of the sol-gel technique using tetraethylorthosilicate (TEOS) as silicon source and glycerol (Gly) and glycerol monostearate (ME) as templates, which have low cost and wide commercial availability. The so-obtained silicas have many interesting porous characteristics for potential applications in heterogenous catalysis: specific surface area (BET method) of 736.3 m²/g, total porous volume of 0,41 cm³/g and pore size narrows distribution (BJH method) around 36 Å

Keywords : Template; glycerol; glyceryl monostearate; silicon oxides; porous silica; sol-gel technique; tetraethylorthosilicate.
