摘要：
To address issues of global energy sustainability, it is of great practical significance to develop low cost and high efficiency electrocatalysts for the oxygen evolution reaction (OER). In this work, we synthesize amorphous Co1-xVxSy nanosheets using Co1-xVx-MOF/NF as a precursor to explore the structural evolution of metal-organic framework (MOF) derivatives during the OER. When tested for OER performance in 1.0 M KOH solution, Co0.9V0.1S0.002/NF exhibits the best catalytic activity, with an overpotential of only 194 mV at a current density of 20 mA cm(-2) and a Tafel slope of 28.4 mV dec(-1). We also measured the long-term electrochemical durability of Co0.9V0.1S0.002/NF and found that Co0.9V0.1S0.002/NF maintains its stability for at least 100 h at a current density of 20 mA cm(-2).
