Abstract

Highlights

The heterogeneous interface of NiO/Co₃O₄ was constructed for regulating adsorption behavior of urea functional groups.
The regulation mechanism of urea molecular adsorption behavior was verified by temperature-programmed desorption experiments and density functional theory calculations.
Efficient and scalable electrocatalytic urea wastewater treatment coupled with hydrogen production was realized in anion exchange membrane water electrolyzer AEMWE, which can continuously treat urea wastewater at an initial current density of 600 mA cm^-2, with about 53% in average urea treatment efficiency.

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.
