Sintering of Ni particles in the Ni-based anode is a major obstacle to the widespread use of solid oxide fuel cell because the sintering induces the degradation in the anode. The large amount of water vapor in the fuel is known to accelerate the degradation during the operation. However, the detailed accelerated sintering mechanism is unclear. In this study, to clear the accelerated sintering mechanism...
Water adsorption and dissociation on catalytic metal surfaces play a key role in a variety of industrial processes, and a detailed understanding of this process and how it is effected by the surface structure will assist in developing improved catalysts. Hence, a comparative study of the adsorption and dissociation of water on Ni(111), Ni(110) and Ni(100) surfaces, which is often used as catalyst,...
This paper has researched on the adsorption of Ni in water using Laminaria japonica and Undaria pinnatifida. The dependence on pH and nickel concentration of the adsorption was studied. Batch experiments results showed that the adsorptive capacity of Laminaria japonica and Undaria pinnatifida was 2.933mg/g and 0.985 mg/g of adsorbent. The Langmuir model was used to describe the adsorption equilibrium...
Periodic DFT calculations using plane waves basis sets with the GGA formalism were performed in order to study the behavior of the UO22+ uranyl ion at the water–Ni(111) interface. First, the adsorption of water molecules interacting with an optimized surface model has been studied. At low coverage, isolated water molecules adsorb preferentially on top of the surface nickel atoms, the plane defined...
