摘要

本文研究了不同γ射线照射剂量下，钙钛矿型LaCoO,3,催化剂材料中二价钴离子，化学吸附氧含量的变化规律，以及对CO催化氧化反应的影响，并探讨了反应机理。

Abstract

In this paper, effect of ,60,Coγ-irradiation on the catalytic activity of perovskite rare earth cobaltites LaCoO,3, for CO oxidation reaction has been studied.,The Co,2+, and chemisorption oxygen content in the LaCoO,3, catalyst increased with increasing γ-dose. It was also found that the catalytic activity for CO oxidation is proportional to the bivalent cobalt ion in LaCoO,3,. A mechanism involving the bivalent state of Co has been proposed to explain these results.
