摘要

首次开发了一种开创性的化学发酵产孔机制，用于在碳结构中产生纳米孔，形成基于气化和凝固之间最佳平衡的多级多孔网络。Ni - Fe@C1D@2D多孔网络表现出优异的析氧反应电催化性能，在无负载惰性电极上实现了10 mA cm - 2下165 mV的超低过电位，并保持了超过90小时的长期稳定性。

Chemical Fermentation PoreCreation on Multilevel Bio-Carbon Structure with In Situ Ni–Fe Alloy Loading for Superior Oxygen Evolution Reaction Electrocatalysis

Highlights

A groundbreaking chemical fermentation pore-generation mechanism is developed for the first time for creating nanopores within carbon structures to form multilevel porous network based on the optimal balance between gasification and solidification.
The Ni–Fe@C_1D@2D porous network demonstrates an exceptional oxygen evolution reaction electrocatalytic performance, achieving an ultralow overpotential of 165 mV at 10 mA cm⁻² on a non-supported inert electrode and maintaining long-term stability for over 90 h.

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.
