Electrospun noble metal-based nanofibers for water electrolysis

Abstract

The rational preparation of efficient and durable electrocatalysts is the key to advancing the development of water electrolysis technology. Noble metal-based materials, such as Pt, Ru, and Ir, have excellent catalytic performance and stability. However, their high cost and low abundance require researchers to explore effective strategies to improve their utilization efficiency.Electrospinning is a facile synthetic method to prepare one-dimensional nanofibers with the desired composition and structure, especially carbon-supported metal-based electrocatalysts with a large specific surface area and high conductivity, through post-processing strategies. This review introduces the recent progress in electrospinning to prepare noble metal-based catalysts for water electrolysis. Specifically, we summarize various strategies for incorporating noble metals into electrospinning nanofibers, as well as their electrocatalytic performance towards hydrogen evolution, oxygen evolution, and overall water splitting. Finally, we proposed the opportunities and challenges faced by electrospinning technology in the creation of water electrolysis catalysts, as well as the prospects for future development.
