Novel Electrocatalysts for Highly Efficient Hydrogen Production

Updated: May 13

Webinar Series for GlobH2E, co-hosted by the Powerfuels including Hydrogen Network of the NSW Decarbonisation Innovation Hub.





Abstract

The need to develop highly efficient catalysts to improve electrochemical performance is growing significantly due to the ever-increasing demand for energy conversion devices in the last few decades. Electrochemical water electrocatalysis for hydrogen production is one of the representatives for the next-generation energy conversion. However, the electrochemical performance is still not satisfying to be potentially used in industrial applications. Here, I present our research on catalyst engineering strategies for energy conversion reactions, including electronic structure engineering and atomically dispersed metal engineering. For instance, we show the stable construction of atomically dispersed precious metal-based catalysts, which exhibit maximum efficiency towards the electrochemical performances of hydrogen production. The in-situ exfoliated MXene coupled with Pt single atoms showed high hydrogen generation performance with a mass activity more than 40 times higher than the commercial Pt/C. Most recently, our work on constructing electrocatalysts in the condition of acidic environments and sea water display excellent performance for hydrogen production. Here, recent highlights regarding the engineering strategies, electrocatalysts and their applications will be presented.
