  • 摘要:The development of high performance bi-functional electrocatalysts for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) with low cost materials has remained a great challenge in electrochemical water splitting. Herein, we design and develop novel Co-doped Fe0.95S1.05 nanoplates, which were synthesized using Fe(CO)(5) as precursor for the first time via a one pot reaction. Fe0.9Co0.05S1.05 lead to enhanced OER activity with a low overpotential of similar to 0.27 V at 20 mA/cm(2), small Tafel slope of similar to 46 mV/decade, as well as improved HER activity with a Tafel slope of 114 mV/decade and a current density of 20 mA/cm(2) at an overpotential of similar to 0.385 V. This study produced the most active pyrrhotite FeS based catalyst for electrochemical water splitting, which suggests a scalable, low cost, simple, and highly efficient catalyst for water splitting.
