Ordered mesoporous catalysts could open the door for new catalytic processes, based partly
on novel principles, owing to their hitherto unprecedented intrinsic features. For the …

This review addresses the most relevant aspects of vibrational spectroscopies (IR, Raman
and INS) applied to zeolites and zeotype materials. Surface Brønsted and Lewis acidity and …

A very large number of different synthesis approaches for the preparation of mesoporous
materials has been reported in literature since the first development of ordered mesoporous …

Very frequently the most costly components in a chemical reaction are not the starting
materials or the reaction products, but the catalyst. In addition to the advantages from the …

Further progress in the field of heterogeneous catalysis depends on our knowledge of the
nature and behavior of surface sites on solid catalysts and of the mechanisms of chemical …

This paper describes the most used techniques in the determination of the acid property in
zeolite materials. Two families of techniques, namely spectrometric (IR, NMR) and …

A novel application of Fe–Zn double-metal cyanide (DMC) complexes as solid catalysts in
the preparation of fatty acid alkyl esters (biodiesel/biolubricants) from vegetable oils is …

The mesoporous silica have been considered fascinating materials for many techonological
applications due to their porous and morphological characteristics. This review focuses on …

Zeolites and amorphous silica-alumina (ASA), which both provide Brønsted acid sites
(BASs), are the most extensively used solid acid catalysts in the chemical industry. It is …

M41S is the designation of a new type of mesoporous structures. The characteristics of these
materials are large surface areas and very narrow pore size distributions, with pore …
