Abstract

In this work, NiFe LDH/Ti3C2Tx/Nickel foam (NF) was successfully prepared as a binder-free electrode by depositing NiFe layered double hydroxide (LDH) nanosheets on Ti3C2Tx/NF substrate through electrodeposition approach. The strong electrostatic interactions between the negatively charged surface of MXene and positively charged NF substrate enabled the direct growth of NiFe LDH nanosheets on Ti3C2Tx/NF substrate. As a result, the as-prepared NiFe LDH/Ti3C2Tx/NF electrode exhibited an excellent OER performance, fast catalytic reaction kinetics and good chemical stability. Its overpotential reached 200 mV at a current density of 10 mA cm−2, and the cycling tests suggested a good cycling stability.
