Abstract:
Developing highly efficient and stable electrocatalysts toward the oxygen evolution reaction (OER) is essential for large-scale sustainable energy conversion and storage technologies. Herein, we design and synthesize a ruthenium (Ru) doped NiFe bimetallic metal-organic framework (MOF) deposited on the nickel foam (Ru-NiFe-MOF/NF) by a facile one-pot hydrothermal reaction. Ru-NiFe-MOF/NF exhibits favourable electrocatalytic OER activity in alkaline solution, and requires a low overpotential of 205 mV to achieve 10 mA cm-2, a small Tafel slope of 50 mV dec-1, and long-term electrochemical stability over 100 h. This work demonstrates the rational nano-architectural design and synthesis of predominantly efficient and robust cation-doped MOF-derived materials for energy catalysis and beyond.
