TL;DR: The encapsulation of homogeneous chiral catalysts in the mesoporous cage of SBA-16 is demonstrated; the encapsulated catalysts show performance as good as that of the homogeneous catalysts, and can be recycled for more than 10 times without significant loss of catalytic performance.

TL;DR: In this article, the number and strength of Bronsted acid sites were determined quantitatively by a method of infrared-mass spectroscopy/temperature-programmed desorption (IRMS-TPD) of ammonia.

TL;DR: Synthetic methods for making an all-silica MCM-41 mesoporous silicate of high long-range order are reported in this article, which shows up to seven orders of X-ray diffraction and good stability under calcination conditions.
Abstract: Synthetic methods for making an all-silica MCM-41 mesoporous silicate of high long-range order are reported. The product shows up to seven orders of X-ray diffraction and good stability under calcination conditions. The greatest improvement in structure occurs when the pH is held between 9 and 10 during synthesis and the sulfate anion is present.

TL;DR: In this article, high-ordered mesoporous material (Bu4N)4H3(PW11O39)/MCM-41 with 10, 18, and 25.5% loadings was prepared by impregnation method in acidic media under reflux conditions, and characterized by XRD, HRTEM, Nitrogen adsorption/desorption, FT-IR, 31P CP-MAS NMR, XPS, SEM and TEM.
