Abstract

Highlights

Atomically dispersed Zn-anchored 3D sponge-like polymeric carbon nitride (Zn-PCN) characteristic of a unique Zn-N₆ electron-deficient configuration is synthesized via an intermediate coordination strategy.
The electron-deficient Zn-N₆ configuration contributes to enhanced electron excitation, accelerated charge separation and transfer as well as reduced overpotentials of water redox reactions.
The obtained Zn-PCN realizes photocatalytic overall water splitting to stoichiometrically produce H₂ and O₂ with good durability under visible light.

缺电子的 Zn-N6 构型可使聚合物氮化碳用于可见光光催化整体水分离

亮点通过中间配位策略合成了原子分散的 Zn 锚定三维海绵状聚合氮化碳（Zn-PCN），它具有独特的 Zn-N6 缺电子构型。缺电子的 Zn-N6 构型有助于增强电子激发、加速电荷分离和转移以及降低水氧化还原反应的过电位。所获得的 Zn-PCN 可实现光催化整体水分离，按比例产生 H2 和 O2，并在可见光下具有良好的耐久性。

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.
