Summary: Ce doping and pretreatment of Pt/Al2O3 catalysts were studied for catalyzing propane oxidation after aging. A small amount of Ce doping enhanced the dispersion of Pt nanoparticles and inhibited sintering, leading to improved oxidation activity. Ce species with less than 3.6 wt% were highly dispersed and critical for promoting propane oxidation.

Summary: The methane oxidation and oxygen storage capacity of a bilayer Pt/Pd/Al2O3 over a Mn0.5Fe2.5O4 spinel catalyst under periodic conditions were studied before and after SO2 exposure. Improvement in CH4 oxidation conversion was observed under periodic conditions compared to steady-state conditions before sulfur exposure. After sulfur exposure, a loss in CH4 oxidation performance and oxygen storage capacity of the spinel material was observed, but regeneration methods under periodic conditions led to improved CH4 conversion.

Summary: This study investigates the catalytic performance of Cr2O3/Al2O3 catalysts with different loadings and calcination processes in the dehydrogenation of propane. The results show that the catalysts calcined by air achieved higher propane conversion, while those calcined by H2/Ar exhibited better anticoking ability and resistance against deactivation. The difference in catalytic performance is attributed to the nature of Cr species, the dispersion, and the surface acidity.

Summary: This study found that Rh catalysts supported on Al2O3-based oxides lose their catalytic activity when exposed to high-temperature oxidizing environments. The diffusion of Rh3+ ions into the support structure causes substantial thermal deactivation. However, the layered structure of LaMgAl11O19 hinders the diffusion of Rh3+, preserving the catalytic activity.

Summary: When Rh catalysts supported on Al2O3-based oxides are exposed to a high-temperature oxidizing environment, they lose their three-way catalytic activity due to the diffusion of Rh3+ into the support structure. The diffusion of Rh3+ is suppressed in the layered structure of hexaaluminate, which effectively blocks further penetration and preserves their reduction to active metallic Rh nanoparticles.

Summary: Co-based catalysts on Al2O3 support with different compositional distribution of Co species were prepared by heat-treating the precursor under O2, Ar, and H2 atmospheres. The H2-treated catalyst showed superior PDH performance due to higher Co surface concentration and higher ratio of tetrahedral Co2+ in Co-Al2O4. Both tetrahedral Co2+ and metallic Co were found to be active for PDH, with the former showing higher selectivity.

Summary: In this study, Ga/gamma-Al2O3 catalysts were evaluated for propane dehydrogenation (PDH). The results showed that the selectivity of propylene decreased with increasing propane conversion. It was found that propylene is a primary product, while light gas by-products are secondary products. The study also confirmed that the same light gas products can be produced by a direct reaction of propylene.

Summary: Catalyst stability, resistance to deactivation, and regeneration are major challenges for high temperature reactions. This study investigates Pt alloys for propane dehydrogenation (PDH) and finds that silica-supported catalysts show excellent selectivity but their regenerability is uncertain. Oxidation in air and treatment in hydrogen can restore the lost catalytic activity, and in situ temperature programmed oxidation reveals two types of coke formed on these catalysts: one on the metal nanoparticle surface and another on the silica support. This work suggests that periodic introduction of hydrogen may prolong the lifetime of PDH catalysts.

Summary: Materials capable of emitting UV radiation under NIR excitation are highly desirable for various applications. This study investigates the size, structure, and luminescence properties of tetragonal LiY(Gd)F-4 nanocrystals doped with different concentrations of Gd3+ ions. The results demonstrate that low concentrations of Gd3+ ions can modify the size and up-conversion luminescence, while excess doping leads to the appearance of foreign phases and a significant decrease in luminescence intensity. The intensity and kinetics of Gd3+ up-converted UV emission are also analyzed. These findings provide a foundation for the development of optimized materials and applications based on LiYF4 nanocrystals.
