摘要：

The sluggish anodic oxygen evolution reaction (OER) greatly hinders the working efficiency of electrochemical water splitting to produce hydrogen, and it is therefore important to explore high-performance and cost-effective OER catalysts. In this communication, we report the synthesis of cobalt boride incorporated within porous carbon using a metal-organic framework (MOF) as a precursor. The high catalytic activity of Co-B and the high conductivity of carbon both contribute to the OER catalytic activity of Co-B/C. When used as an OER catalyst, this material shows high catalytic activity, delivering a current density of 10 mA cm(-2) at a low overpotential of 320 mV, as well as outstanding long-term electrochemical durability. This finding is of fundamental and practical importance as it not only extends the application of MOFs, but also introduces a new method for synthesizing highly efficient OER electrocatalysts.
