超薄NiFe-层状双氢氧化物(LDH)纳米片的制备方法简单，成本效益高。所制备的NiFe-LDH纳米片是一种在碱性环境中对水氧化具有高活性和稳定性的电催化剂，表现出更高的析氧活性和更低的过电位，稳定性增强，远远优于以往报道的LDH衍生催化剂。这项工作为制备纳米薄片提供了一种简便的方法，在可再生能源转换中具有很好的应用前景。
Ultrathin NiFe-layered double hydroxide (LDH) nanosheets are facilely and cost-effectively fabricated. The as-prepared NiFe-LDH nanosheets are highly active and stable electrocatalysts for water oxidation in alkaline environment, exhibiting a much higher oxygen evolution activity and lower overpotential with the enhanced stability, much superior to the previously reported LDH-derived catalysts. This work provides a facile methodology for the fabrication of thin nanosheets, which are promising in the renewable energy conversion.
