| 英文摘要 | Individuals experiencing poverty and possessing limited financial resources are particularly susceptible to impacts of climate change and rising costs associated with fossil fuels. In response to this pressing issue, researchers are actively investigating water oxidation as a sustainable solution to mitigate the challenges posed by climate changes and energy crisis. The oxygen evolution reaction (OER), which plays a pivotal role in water electrolysis, necessitates the utilization of highly stable and efficient electrode materials to overcome its intrinsic sluggish kinetics and enhance the overall efficiency of the electrochemical device. This investigation employed a reduction method to synthesize manganese oxide (MnO) nanoparticles, using manganese telluride (MnTe) as the base material, yielding a MnTe@MnO nanocomposite. This innovative composite was subsequently immobilized onto a nickel foam (NF) substrate. Remarkably, the MnTe@MnO nanocomposite exhibited exceptional OER performance in a 1.0 M alkaline solution, manifesting an impressively low overpotential of 208 mV at a benchmark current density of 10 mA cm-2. This overpotential significantly surpassed that of the individual MnTe and MnO electrode materials, underscoring the synergistic advantages of the MnTe@MnO nanocomposite. Further analysis revealed a notably shallow Tafel slope of 39 mV dec-1, indicative of the enhanced reaction kinetics and electrocatalytic efficiency inherent to the MnTe@MnO nanocomposite. Moreover, the durability assessment over a span of 30 h demonstrated minimal current loss, emphasizing the substantial electrocatalytic active surface area of the fabricated nanocomposite. |
