用自由正电子固体表面态湮没技术研究2%PdO/Al_2O_3

A STUDY ON THE 2% PdO/Al_2O_3 BY MEANS OF FREE POSITRON ANNIHILATION TECHNIQUE IN THE SOLID SURFACE LAYER

用~22Na的e^+研究2%PdO/Al_2O_3中PdO空间结构与热处理的关系,利用e^+湮没参数计算PdO颗粒度,说明自由e^+固体表面态湮没技术可以应用于催化剂的研究。

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.
