Summary: The development of efficient oxide-supported bimetallic catalysts is crucial for ammonia synthesis or other hydrogen-involved reactions. In this study, ceria-supported Co-Mo bimetallic catalysts with different properties were designed by changing the addition of Mo, resulting in enhanced ammonia synthesis activities. It was found that the negative effect of molybdenum oxide on the reduction of the bimetallic catalyst could be effectively alleviated by the subsequent addition of Mo species, leading to improved catalyst activity.

Summary: In this study, a new composite Co-Mo bimetallic sulfide supported on carbon cloth (MoS2/CoS2/CC) was prepared via a one-pot hydrothermal sulfurization strategy as an efficient electrocatalyst for boosting hydrogen production from water electrolysis. The obtained MoS2/CoS2/CC catalyst exhibited outstanding hydrogen evolution reaction (HER) ability, with a low overpotential of 69 mV at a current density of 10 mA cm(-2) in KOH solution, comparable to advanced Pt/C electrodes. Moreover, the catalytic electrode showed excellent stability in the electrolyte of 1.0 M KOH, as confirmed by XRD analysis after the catalytic reaction.

Summary: The Ni-Mo/Al2O3 catalyst calcinated using infrared radiation heating showed superior catalytic performance in the HDS of shale oil, resulting in lower sulfur content in the product oil compared to the catalyst calcinated in a conventional electric furnace. Characterization of the catalysts revealed that the infrared-heating catalyst had higher BET surface area, smaller and narrower metal particle size distribution, higher binding energy between Mo and S, and more oxygen-deficient sites than the conventionally heated catalyst.

Summary: The mechanism of photochemical reduction of carbon dioxide to carbon monoxide coupled to hydrocarbon dehydrogenation catalyzed by a three-component hybrid construct has been studied. This process involves electron and proton coupled transfer, with visible blue light absorbing by graphitic carbon nitride to transfer electrons to polyoxometalate (POM). The reduced POM then transfers electrons to a bimetallic rhenium CO2 reduction catalyst under red light irradiation, leading to the reduction of CO2 to CO.

Summary: The co-processing of RSO-SRGO mixture over Mo/Al2O3-CoMo/Al2O3-SAPO-11 and Mo/Al2O3-NiMo/Al2O3-SAPO-11 catalytic systems resulted in decreased cloud point of products as temperature increased, with differences observed in the behavior under varying pressure. The hydrogenated products produced over NiMo/Al2O3-SAP showed lower final boiling point values and aromatic content compared to those produced over CoMo/Al2O3-SAP catalyst. Unexpectedly, pressure had varied effects on cloud point and conversion of long chain alkanes in the hydrodeoxygenation of RSO.

Summary: Total X-ray scattering and atomic pair distribution analysis were used to study the structure of anisotropic two-dimensional MoS2 nanoparticles in MoS2/Al2O3 catalysts. PDF analysis not only helped determine atomic ordering, but also assess the geometry and size of the nanoparticles. Discrete atomistic modeling was used in refinement of PDFs to account for finite size and shape effects, revealing that MoS2 slab length was smaller than values obtained from high-resolution TEM data due to defectiveness and multi-domain structure of the nanoparticles. The study also suggested that increasing the heat treatment temperature of oxide precursors decreased deformation of MoS2 nanoparticles in sulfided catalysts.
