摘要：

There is a demand for non-precious-metal-carbon composites for use as oxygen reduction reaction (ORR) catalysts. Herein, we report the use of a sealed-tube reactor system to prepare carbon composites from metal-organic framework (MOF) precursors and to optimize its BET surface area, electric conductivity, and metal/nitrogen distribution, which all contribute to ORR performance. [Co(2-methylimidazolate)(2)](n) (ZIF-67) was sealed in a quartz tube and calcined to fabricate a cobalt-carbon composite. The optimized catalyst showed excellent ORR properties that are comparable to those of the Pt/C benchmark (electron-transport number, 3.95; current density = 33.2 mA cm(-2)).
