Deactivation mechanism for water splitting: Recent advances

Hydrogen (H2) has been regarded as a promising alternative to fossil-fuel energy. Green H2 produced via water electrolysis (WE) powered by renewable energy could achieve a zero-carbon footprint. Considerable attention has been focused on developing highly active catalysts to facilitate the reaction...

Green H2 produced via water electrolysis (WE) powered by renewable energy could achieve a zero-carbon footprint. Considerable attention has been focused on developing highly active catalysts to facilitate the reaction kinetics and improve the energy efficiency of WE.

In this review, we first discuss the WE mechanism, including anodic oxygen evolution reaction (OER) and cathodic hydrogen evolution reaction (HER).

Finally, the influence of fluctuating energy on catalyst degradation is highlighted and in situ characterization methodologies for understanding the dynamic deactivation processes are described. The stability of electrocatalysts has a significant influence on energy efficiency and productivity for industrial green hydrogen production. This review highlights recent research advances regarding the deactivation mechanism in water electrolysis and related in situ/operando techniques for dynamic mechanism studies. image Wiley 2024-07 Article PeerReviewed Jia, Yansong and Li, Yang and Zhang, Qiong and Yasin, Sohail and Zheng, Xinyu and Ma, Kai and Hua, Zhengli and Shi, Jianfeng and Gu, Chaohua and Dou, Yuhai and Dou, Shixue (2024) Deactivation mechanism for water splitting: Recent advances.
