文摘
- •
DO* and kO* for undoped, Fe- and Ni-doped mayenite were determined by an oxygen isotope exchange experiment.
- •
Surprisingly, cation doping with a dopant concentration of 1 mol% has no detectable effect on the oxygen tracer diffusion.
- •
The oxygen surface exchange remains unaffected by cation doping, which suggests that the framework is not directly involved.
