Researchers have designed a simple method to construct the coupling structure of m-NiFe@MnO2 ultra-thin nanosheet for oxygen evolution reaction on nickel foam, showing excellent OER performance and stability.
A simple method has been designed for constructing the coupling structure of m-NiFe@MnO2 ultra-thin nanosheet for oxygen evolution reaction on nickel foam. Intervention of the active component NiFe hydroxide not only promotes the dissociation of water but also reduces the energy barrier of the intermediate, while the presence of subsequent microwaves accelerates the electron transfer. m-NiFe@MnO2 showed excellent OER performance. This is prominently manifested in that when the current density reaches 100 mA cm(-2), the overpotential is only 310 mV, which is far better than RuO2. The long-term (>= 100 h) durability test also further proves its excellent stability.
