Abstract:
Metal organic frameworks (MOF) electrocatalysts for the oxygen reduction reaction (ORR) were synthesized by a hydrothermal process using cobalt salts as the metal ion precursors.The bifunctional catalytic activities of metal organic framework (MOF) toward the oxygen reductionreaction(ORR) in alkaline electrolyte were investigated by cyclic voltammetry (CV) and linearsweep voltammetry (LSV).The results demonstrate that the as-prepared MOF has a good crystalline structure with abundant micropores, a high specific surface area and a high thermal stability. MOFs exhibit excellent bifunctional catalytic activities for ORR. The high specific surface area andabundant micropores are beneficial for oxygen diffusion and catalytic sites utilization in the catalyst, which is favorable for the ORR. The electrochemical measurements were carried out in alkaline medium. The synthesized MOF/CNT composite showed a comparable activity with Pt/C.
