英文摘要: In this work, carbon-supported cobalt monoxides with an average size of 3.5, 4.9, and 6.5 nm are synthesized via a facile colloidal method avoiding any surfactants of long chains. Along with controlling the CoO particle size, we investigate the dependence of ORR activity on particle size of the CoO/C composite. It is discovered that the turnover frequency of the ORR per CoO site is largely independent of the particle size in the range of 3-7 nm, and the enhanced ORR activity for the smaller CoO particles is attributed to the enlarged interface between CoO and carbon.
