Resumen

A mixture of sodium dehydrocholate (NaDHC) and hexadecyltrimethylammonium bromide (HDTAB) was employed as a template to produce mesoporous silica. The obtained material shows the same structure as common MCM-41 sieves, but the pore radius distribution is narrower than that of the material produced with the same concentration of pure HDTAB. The average pore radius is also larger than that of the pure HDTAB-templated material.
