Unraveling the Origin of Exceptional Activity in NiMo Alloys for Alkaline Hydrogen Evolution
Advanced Science, EarlyView.This study resolves the controversy regarding the active origin of Nickel‐molybdenum (NiMo) alloys for alkaline hydrogen evolution. By combining surface Pourbaix diagrams with microkinetic modeling, we demonstrate that the O‐covered Ni3Mo surface drives activity through a synergistic mechanism: Mo sites facilitate water dissociation while adjacent Ni ...

Activity of Spent Catalysts in the Hydrodesulfurization of Gas Oil [PDF]
, 2013 Activities of spent catalysts were examined in hydrodesulfurization (HDS) of gas oil at 340oC under 50 kg/cm2 H2. Two types of spent commercial catalyst (NiMo/Al2O3 dan CoMo/Al2O3) were used in single and two-stage of reaction configuration to show the ...
