摘要：

The variation of the activation enthalpy for surface oxygen exchange 1/2O2 + VO..⇄OOx + 2 h. with sample composition in (Ln,Sr)(Mn,Fe,Co)O3-z perovskites is rigidly coupled to the variation of the overall reaction enthalpy (see picture). This is the first mechanistically well-established example of a Hammett-like relationship for inorganic gas-solid reactions.
