2-step reaction kinetics for hydrogen absorption into bulk material via dissociative adsorption on the surface

open access: yesScientific Reports, 2021
We have demonstrated that the process of hydrogen absorption into a solid experimentally follows a Langmuir-type (hyperbolic) function instead of Sieverts law. This can be explained by independent two theories.
