水分解为解决由于化石燃料消耗而产生的问题提供了一种有前途的、可持续的方法。这需要开发低成本、高性能的电极材料。析氧反应（OER）是水裂解过程中的一个关键反应。镍钴复合氧化物形成了过电位小、OER动力学快的纳米结构。与贵金属氧化物（如RuO2和IrO2）相比，它们具有理论上的高效率、高丰度、低成本和环境友好性，引起了人们的广泛关注。然而，期望的效率需要提高比活性面积和电导率的发展。在当前的沟通中，我们解决了这些问题。具体地说，采用层双氢氧化物（LDH）的剥离来提高活性表面积。研究表明，杯芳烃在NiCo LDH中的嵌入提供了一个多功能的中间层，提供了大的活性表面积和快速的电子传递。
Water splitting provides a promising, sustainable way to resolve problems arising due to depleting fossil fuels. The success needs development of low-cost and high-performance electrode materials. The oxygen evolution reaction (OER) is a crucial reaction in water splitting. The combined Ni and Co oxide developed nanostructures having a small overpotential and fast kinetics of OER. They have drawn considerable attention, because of their theoretically high efficiency, high abundance, low cost, and environmental benignity in comparison with precious metal oxides, such as RuO2 and IrO2. However, the desired efficiency needs the developments of enhanced specific active area and conductivity. In the present communication, we address these issues. Specifically, exfoliation of layer double hydroxide (LDH) is applied to enhance the active surface area. The study reveals that intercalation by calixarene in NiCo LDH affords a multifunctional interlayer to deliver a large active surface area and fast electron transp...
