TL;DR: In this article, a selective water sorbent based on mesoporous KSKG silica gel as a host matrix and lithium bromide as a hygroscopic salt is presented.
Abstract: This paper presents sorption properties of a selective water sorbent based on mesoporous KSKG silica gel as a host matrix and lithium bromide as a hygroscopic salt. Sorption isobars, isochores and isotherms measured at T=40–120°C and partial vapor pressures of 7.5–81.0 mbar indicated two types of water sorption: 1) formation of a solid crystalline LiBr monohydrate at low amounts of sorbed water, and 2) vapor absorption by the salt solution at higher sorptions. Sorption properties of the LiBr monohydrate are found to change significantly due to salt impregnation into the mesoporous silica gel, whereas the solution confinement to the mesopores did not change its water sorption properties as compared to the bulk solution. Desorption curves follow a first order kinetics in the temperature range of 60–130°C at different vapor pressures.

TL;DR: In this paper, the structure and adsorption properties of new carbon carriers obtained on the basis of carbon black have been examined, and the new material is of interest for fundamental studies of carbon-supported catalysts.
Abstract: Structure and adsorption properties of new carbon carriers obtained on the basis of carbon black have been examined. These carriers possess largely mesoporous structure, developed surface and high mechanical strength and contain hollow globules. Walls of these globules have pores, whose size is several hundreds A. The new material is of interest for fundamental studies of carbon-supported catalysts.

TL;DR: In this paper, the ZSM-5 zeolite matrix (α-centers) was shown to perform single-turnover cycles of methane oxidation to methanol at room temperature when nitrous oxide is used as a source of oxygen.
Abstract: Iron complexes in the ZSM-5 zeolite matrix (α-centers) are shown to perform single-turnover cycles of methane oxidation to methanol at room temperature when nitrous oxide is used as a source of oxygen. The origin of carbon and oxygen in the product methanol was traced using13C and18O isotopes. Probable structure of α-sites as well as mechanistic features of the reaction allow to consider this system as a first successful model of methane monooxygenase.

TL;DR: In this paper, the authors showed that Au/H-ZSM-5 catalyst can partially inhibit carbon deposition during the reaction, thus maintaining constant catalytic activity for BTX formation.
Abstract: H-ZSM-5 (Si/Al2 = 29) zeolite showed especially high activity in the conversion of ethanol to BTX (benzene, toluene, xylenes), while other zeolites exclusively formed ethylene. Noble metal catalysts supported on H-ZSM-5 (29) zeolite have high activity for the formation of BTX. Of these, Au/H-ZSM-5 catalyst can partially inhibit carbon deposition during the reaction, thus maintaining constant catalytic activity for BTX formation.
