摘要：

It's highly desirable to devise and develop non-precious metal catalysts for efficient water oxidation catalysis in alkaline solution. Herein, we report Co-MOF nanosheet arrays grown on the three dimensional conductive nickel foam (Co-MOF/NF) through a hydro-thermal process for efficient alkaline oxygen evolution electrocatalysis. Such catalyst displays an excellent electrochemical performance by achieving an overpotential of 290 mV at 20 mA cm(-2) in 1.0 M KOH. Besides, it possesses both a good electrochemical stability and a high turnover frequency of 0.14 s(-1) at the overpotential of 400 mV.
