The Origin of the Catalytic Activity of a Metal Hydride in CO2
... catalytic reaction is greatly influenced by the atomic hydrogen out of the metal hydride. The total amount of the formation of methane is linearly related to the hydride composition (Figure 5), although the thermal stability of hydrogen atoms in the metal hydride (i.e. hydrogen equilibrium pressure) ...

... We will estimate the electrical field between an ionized donor atom and a negatively charged vacancy, and its effect upon diffusion. Assume a Si crystal at 1000 °C. The donor atom and vacancy will interact by Coulomb forces. We will calculate the corresponding electrical field for different separati ...
