摘要：
Size effects were found to influence the low-temperature oxidation of Co nanoparticles. These effects were likely caused by the predominant formation of oxide phase nuclei on edge and vertex Co nanocrystal atoms. The initial rate of oxidation was proportional to the degree of nanoparticle surface coverage with atomic oxygen. The magnetic method was used to determine the size of Co nanoparticles. The results were close to those obtained by transmission electron microscopy.
