    Bin Zhang (Department of Chemistry, School of Science, Tianjin University) received his Ph.D. degree from the University of Science and Technology of China in 2007 (with Prof. Yi Xie). He carried out postdoctoral research at the University of Pennsylvania (July 2007 to July 2008, with Prof. Ritesh Agarwal) and worked as an Alexander von Humboldt fellow at the Max Planck Institute of Colloids and Interfaces (August 2008 to July 2009, with Dayang Wang). Currently, he is a Fellow of the Royal Society of Chemistry (FRSC), a senior member of the Chinese Chemical Society, and a professor at Tianjin University. He mainly focuses on the controlled chemical transformation synthesis of designed targeted nanomaterials for water splitting and water-involved transfer hydrogenation reactions. In January 2021, he joined in Youth Editorial Board of the Chinese Journal of Catalysis.

Abstract:

Electrochemical water splitting, as a promising method for hydrogen production, has attracted significant attention. However, the lack of an electrocatalyst with a small energy loss and fast reaction kinetics has hindered the development of this technology. Amorphous nanomaterials with short-range order and long-range disorder features have recently shown superior activity compared to their crystalline counterparts in water electrolysis. The enhanced activity arising from their intrinsic disordered structure results in more active sites and a higher intrinsic activity of such sites. In this regard, this review is aimed at summarizing the progress in amorphous electrocatalysts for water splitting. First, the synthesis strategies for amorphous electrocatalysts are discussed. Characterization tools for amorphous nanomaterials are then summarized. Moreover, the origin of the enhanced activity and stability of amorphous nanomaterials is analyzed. Finally, the current challenges and promising opportunities in this research area are discussed. This review aims to provide a guide for designing and developing amorphous nanomaterials with a fascinating electrocatalytic water splitting performance.
