Abstract

Highlights

Catalytically inert 2D Bi₂O₃ is activated for boosting electrochemical hydrogen evolution reaction (HER) via oxygen vacancy concentration modulation.
The relationship between the varied oxygen vacancy concentrations and the corresponding HER activity is revealed by both experimental V_o verification and theoretical density-functional theory calculations.
This work provides insights into activating catalytically inert materials into high-performance catalysts.

通过氧空位浓度调制，催化惰性二维氧化铋纳米片转化为有效的电化学析氢反应催化

催化惰性的2D Bi2O3被激活，通过氧空位浓度调制促进电化学析氢反应(HER)。通过实验验证和理论密度泛函理论计算，揭示了不同氧空位浓度与相应HER活度之间的关系。这项工作提供了将催化惰性材料活化成高性能催化剂的见解。

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.
