Summary: In this study, the interaction between the surface of ?-Al2O3(110) and NO and H2 was investigated using density functional theory calculations. The results showed that ?-Al2O3(110) can adsorb NO and bind H atoms, but repels H2 molecules. The catalytic activity of ?-Al2O3(110) is provided by a triplet of low-coordinated OII-Al-III-O-II atoms.

Summary: Novel gamma alumina was synthesized by solvent protection and a hydrothermal procedure. The as-synthesized gamma alumina mainly exposes the high-energy crystal plane (111) and shows higher density of surface hydroxyl groups, acid content, and surface energy compared to commercial alumina. The novel gamma alumina exhibited higher yield of ethylene and better stability in industrial ethanol dehydration to ethylene, and steam treatment significantly affected its surface acidity and catalytic performance.

Summary: The kinetics of deactivation of gamma-alumina catalyst in the dehydration of methanol to dimethyl ether were investigated, revealing a second-order independent deactivation kinetics that accurately fit the experimental data. The activation energies for the main reaction and catalyst deactivation were obtained, with the latter showing a negative value due to reversible partial hydration. At higher temperatures, irreversible sintering of alumina crystallites became the predominant deactivation mechanism.

Summary: The SO4/TiO2 catalyst was synthesized with different concentrations of H2SO4 and studied for its activity and selectivity in the dehydration reaction of ethanol to diethyl ether. The catalyst was prepared by wet impregnation of TiO2 powder with various aqueous solutions of H2SO4 and calcined at different temperatures to optimize its acidity. Characterization of the catalyst was done using FTIR, XRD, SEM-EDX, SAA, TGA/DSC, and ammonia gravimetric acidity test. The most active and selective catalyst was found to be TS-3-400 for the reaction, achieving a conversion rate of 51.83% and a DEE selectivity of 1.72% at 225 degrees C.

Summary: The combination of Al2O3 and HAP catalysts generated significant quantities of weak acid sites, enhancing catalytic activity. Pd modification in the optimal composition ratio extremely increased the amount of weak acid sites and density, indicating a synergistic effect between Pd and Al2O3-HAP catalysts in creating active sites. The Al20-HAP80-Pd catalyst showed excellent catalytic performance in producing diethyl ether and ethylene, attributed to weak acid sites, small amount of strong acid sites, and structural characteristics of the catalytic materials.

Summary: In this work, nanosheet MOR (NMOR) zeolite was fabricated using a facile two-step hydrothermal crystallization method. The NMOR zeolite showed better activity and stability in the carbonylation reaction compared to the conventional MOR (CMOR) zeolite. By combining the NMOR and CuZnAl (CZA) catalysts, a more efficient route for ethanol synthesis was achieved. The monitoring of reaction intermediates revealed that the hydrogenation of carbon monoxide (CO) to methanol was suppressed by the hydrogenation of methyl acetate (MA) to ethanol.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
