摘要
催化剂与支撑物之间的相互作用在提高氧进化反应（OER）的催化活性方面起着至关重要的作用。在这里，我们用一种坚固的异质界面调节了聚苯胺支撑的氧化镍三铁（Ni3Fe oxide/PANI）中催化剂与支撑物之间的相互作用，从而显著提高了氧进化活性，在 10 mA cm-2 的过电位为 270 mV，过电位为 300 mV 时比活性为 2.08 mA cmECSA-2，是氧化镍三铁的 3.84 倍。研究表明，Ni3Fe 氧化物与 PANI 载体之间的催化剂-载体相互作用通过界面 Ni-N 键增强了 Ni-O 的共价性，从而促进了 Ni3Fe 氧化物上的电荷和质量转移。考虑到其优异的活性和稳定性，采用最佳的 Ni3Fe 氧化物/PANI 组装了可充电锌-空气电池，在 10 mA cm-2 的条件下，可提供 1.95 V 的低充电电压，循环 400 小时。催化剂与支持物相互作用对催化活性影响的调节为未来设计高效的 OER 催化剂提供了新的可能性。
Catalyst-Support Interaction in Polyaniline-Supported Ni3Fe Oxide to Boost Oxygen Evolution Activities for Rechargeable Zn-Air Batteries.
Catalyst-support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction (OER). Here we modulate the catalyst-support interaction in polyaniline-supported Ni3Fe oxide (Ni3Fe oxide/PANI) with a robust hetero-interface, which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm-2 and specific activity of 2.08 mA cmECSA-2 at overpotential of 300 mV, 3.84-fold that of Ni3Fe oxide. It is revealed that the catalyst-support interaction between Ni3Fe oxide and PANI support enhances the Ni-O covalency via the interfacial Ni-N bond, thus promoting the charge and mass transfer on Ni3Fe oxide. Considering the excellent activity and stability, rechargeable Zn-air batteries with optimum Ni3Fe oxide/PANI are assembled, delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm-2. The regulation of the effect of catalyst-support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.
期刊介绍：
Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand.
Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields.
Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
