A Linear Free Energy Relationship for Gas-Solid Interactions:Correlation between Surface Rate Constant and Diffusion Coefficient of Oxygen Tracer Exchange for Electron-Rich Perovskites

摘要

Reactivity and transport properties can be traced back to materials parameters and control parameters.As far as the concentrations of electronic and ionic charge carriers are concerned,partial pressures P of the components,temperature T,and dopant content C are the most important control parameters.While their influence is often well-understood on a phenomenological level,the understanding of materials parameters such as enthalpies and entropies of reaction or activation usually requires an atomistic analysis.
