摘要

不同功能层的多层结构缓解了光电化学(PEC)制氢的瓶颈。精确的厚度控制在几纳米内，定义了每层的功能。在AM 1.5 G光照下，Bi2S3/NiS/NiFeO/TiO2光阳极在1.23 VRHE下的光电流密度为33.3 mA cm−2。采用NiS阴极和Bi2S3/NiS/NiFeO/TiO2光阳极的集成pec电催化电池进行了无贵金属海水裂解。

Multilayer Strategy for Photoelectrochemical Hydrogen Generation: New Electrode Architecture that Alleviates Multiple Bottlenecks

Highlights

A multilayer architecture of layers with different functions alleviates bottlenecks in photoelectrochemical (PEC) hydrogen generation. Precise thickness control within a few nanometers defines each layer’s functionality.
A Bi₂S₃/NiS/NiFeO/TiO₂ photoanode had a photocurrent density of 33.3 mA cm⁻² at 1.23 VRHE under AM 1.5 G illumination.
Noble-metal-free seawater splitting was performed in an integrated PEC-electrocatalytic cell with an NiS electrocathode and Bi₂S₃/NiS/NiFeO/TiO₂ photoanode.

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.
