TL;DR: In this article, a single-step synthesis of well-ordered MCM-41 materials containing simultaneously alkyl (methyl or propyl) and 3-mercaptopropyl groups has been carried out by hydrothermal treatment of gels containing a mixture of dodecyl and hexadecyltrimethylammonium surfactants.

TL;DR: The synthesis of organized mesoporous aluminas has opened a very interesting area for application of this type of materials, particularly as catalysts or catalyst supports as discussed by the authors, and a review focusing on the individual synthesis routes and evaluation of their textural, chemical and thermal properties is presented in this paper.

TL;DR: In this article, the esterification of glycerol with lauric and oleic acids was carried out by using hybrid MCM-41 materials containing simultaneously alkyl (methyl or propyl) and sulfonic acid groups as catalysts.

TL;DR: In this paper, the authors used tetraethylammonium hydroxide as a structure-directing agent to synthesize SAPO-34 molecular sieves with different structure directing agents, and observed an important influence of the external surface, crystal size and acidity on the activity, selectivity and lifetime of the different samples.

TL;DR: In this paper, mesoporous aluminas were obtained from synthesis gels containing non-ionic surfactants in the presence of dipropylamine, and the pore ordering was observed after calcination at 973 K.
