Publisher Summary This chapter discusses the particular class of molecular sieves, having
periodic mesoporous structure, with pore sizes in the range of 2 to 10 nm. They are …

Nowadays, inorganic–organic hybrid materials having pores in the mesoporous range are
an intensively studied new category of demanding materials. By template synthesis, the …

The nature and concentration of the acid sites of MCM-41 material as a function of Si/Al ratio
have been monitored by in situ IR using pyridine as a probe molecule. The thermal stability …

Catalysis and heterogeneous catalysts are essential to our present technology for the
production and consumption of fuels, the manufacture and processing of chemical …

The catalytic degradation of both low-and high-density polyethylene (LDPE and HDPE) and
polypropylene (PP) has been investigated using MCM-41, a mesoporous aluminosilicate …

The hydrogenation activity of Pt supported on two mesoporous MCM-41 samples differing in
their chemical composition has been studied by following the kinetics of the hydrogenation …

Solids that possess acidic properties on their surfaces function as catalysts just like liquid
acids, such as sulfuric acid and hydrochloric acid. By using solid acid catalysts, chemical …

Up to 73% of the template in MCM-41 can be removed by extraction with solutions of an acid
or salt in ethanol. When extracting with acidic ethanol, ion exchange of the sodium ions for …

Substituted mesoporous MCM-41 materials and transition-metal-free oxides were prepared
and tested as heterogeneous catalysts for the direct conversion of trioses to lactates. This is …

A series of Mo and NiMo catalysts supported on Al-containing MCM-41 was prepared and
characterized by N2 physisorption, XRD, ammonia TPD, temperature programmed reduction …
