Summary: The study focused on the catalytic efficiency of the AlMoGNi catalyst for the HDS of DBT, synthesized by loading Ni promoter on graphene and Mo catalyst on alumina separately, and then combining Ni/graphene with Mo/alumina. The AlMoGNi catalyst showed superior performance in reducing sulfur concentration in fuel compared to catalyst without graphene, attributed to its textural properties, surface acidity, and nanoparticle dispersion. The HDS process over the AlMoGNi catalyst involved hydrogenolysis and hydrogenation desulfurization pathways.

Summary: The Fe-based bulk catalysts modified by SO42-species show improved hydrodesulfurization (HDS) performance for dibenzothiophene (DBT). With increased sulfidation degree, more coordinately unsaturated sites (CUSs) are available for DBT adsorption and desulfurization, resulting in enhanced HDS performance. The introduction of the SO42-species significantly increases the HDS rate of DBT over Fe-Ti bulk catalysts.

Summary: The positive effect of alumina surface graphitization by CVD with ethylene on the activity of CoMo catalysts in hydrodesulfurization has been demonstrated. The simple CVD approach allows selective modification of the surface of commercially available alumina supports with a layer of graphite-like carbon, improving the activity of conventional hydrotreating catalysts. The improved dispersion of supported sulfide component and enhanced promotion of MoS2 by cobalt contribute to the higher hydrodesulfurization activity of CoMoS/C@?-Al2O3 sample.

Summary: This review article explores the unique capabilities of metal chalcogenides (MC) as tailored catalysts in fuel cells. By controlling their morphology and quantity, MC catalysts can enhance the performance of fuel cells. As anodic catalysts, MCs can efficiently oxidize various fuels, while hindering the formation of poisonous species. As cathodic catalysts, MCs exhibit selective reduction of oxygen and provide current values similar to noble metal catalysts.

Summary: We analyze the evolution of coke species on Ni/ZSM-5, beta, and Y zeolites during ethylene oligomerization using high-resolution mass spectrometry. By directly analyzing the used catalysts and their soluble and insoluble coke fractions, we establish a correlation between reaction mechanisms, location of coke, and catalyst performance. Ab initio calculations are performed to understand the preferred location of coke. We investigate the peculiar deactivation mechanism of ZSM-5 zeolite (MFI structure) with two parallel deactivation pathways.

Summary: The production of high-purity, pressurized hydrogen from ammonia decomposition in a membrane catalytic reactor is viable but requires optimization of multiple coupled parameters. The study examines the coupling between catalyst type, process conditions, membrane type, and reactor operation in the catalytic decomposition of ammonia. Results indicate that a holistic approach is necessary to achieve efficient production of pressurized and pure hydrogen, rather than solely optimizing a single factor such as the catalyst.

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.
