In recent years, energy converting and storage systems have been playing a crucial role in alleviating the pressure of energy crisis. Oxygen reduction reactions (ORRs) play an important role in energy converting and storage systems, such as fuel cells and metal air batteries. Herein, it is critical important to develop high efficient and stable electrocatalysts for ORRs to replace platinum-based catalytic materials. In this work, nickel-cobalt bimetallic metal-organic framework (NiCo-MOF-74) and its derivatives (oxides, phosphide and sulfide) were synthesized and their electrochemical performances for ORRs were evaluated. It was found that the series of NiCo-MOF-74 products with rod-like structure show excellent electrochemical performance, especially the sulfide. The sulfide exhibits the onset potential of -0.14V vs Ag/AgCl. Therefore, the series of NiCo-MOF-74 derivatives have great potential in ORRs as highly active, stable, low-cost catalysts.
