In this work, we studied the relationship between heat treatment and space structure of the PdO layer in 2% PdO/AL2O3 by the positrons from 22Na radiative source, and calculated its grain size by the positron annihilation parameters, demonstrating that the free positron annihilation technique for the solid surface layer can be applied to catalyst research.
