摘要：

Dynamics of intrinsic defects are considered fundamental in the chemistry of reducible oxides, and their effect on catalytic reactions have been rarely reported. Herein, we propose a new Ov diffusion assisted Langmuir-Hinshelwood mechanism for CO oxidation, which may largely account for the origin of high reactivity of supported atomic gold catalysts.
