Abstract

Highlights

A hierarchical interconnected NiMoN (HW-NiMoN-2h) was successfully prepared based on a rational combination of hydrothermal and water bath processes.
HW-NiMoN-2h exhibited high hydrogen evolution reaction (HER) activity due to its large specific surface area and good stability due to its enhanced mechanical strength.
In 1 M KOH seawater, HW-NiMoN-2h delivered current density of 1 A cm⁻² for HER at an overpotential of 130 mV and showed excellent stability over 70 h at 1 A cm⁻².

具有大比表面积和高机械强度的分层互连NiMoN用于高效稳定的碱性水/海水析氢

基于水热法和水浴法的合理结合，成功制备了一种层叠互联NiMoN (HW-NiMoN-2h)。HW-NiMoN-2h具有较大的比表面积和较好的稳定性，具有较高的析氢活性。在1 M KOH的海水中，HW-NiMoN-2h在过电位为130 mV时为HER提供了1 A cm -2的电流密度，并在1 A cm -2下保持了70小时的优异稳定性。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
