“…The superior HER electrocatalysis performance resulted from more exposed active sites of graphitic edge plane rich carbon and high conductivity of carbon structure, whereas Co played a role to catalyze formation of carbon structure by graphitization. [ 74 ] Recently, Zhang et al [ 75 ] also synthesized porous N‐doped Co‐CNFs HER electrocatalyst via an electrospun method combined with a controlled carbonization process. The results showed that the carbonation temperature and the additive polyacrylonitrile (PAN) amount had a great influence on the morphology of electrocatalysts.…”

Electrochemical water splitting, as a promising sustainable‐energy technology, has been limited by its slow kinetics and large overpotential. This shortcoming necessitates the design of 1D nanocatalysts with large surface area, high electronic conductivity, and easily tunable composition. Herein, recent progress about electrocatalytic water splitting based on the advanced electrospun nanomaterials is reviewed. First, the related fundamentals of electrochemical water splitting according to two main aspects are discussed as follows: hydrogen evolution reaction and oxygen evolution reaction. Second, the structure design and the electrocatalytic properties of electrospun nanomaterials according to difference in component (including single metal‐based electrocatalysts, metal alloy‐based electrocatalysts, metal oxide‐based electrocatalysts, metal sulfide‐based electrocatalysts, metal phosphide‐based electrocatalysts, metal carbide‐based electrocatalysts, etc.) are summarized. Finally, the future perspectives and challenges for designing next‐generation 1D electrospun nanocatalysts for electrochemical water splitting are concluded.

Nowdays, electrocatalytic water splitting has been regarded as one of the most efficient means to approach the urgent energy crisis and environmental issues. However, to speed up the electrocatalytic conversion efficiency of their half reactions including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), electrocatalysts are usually essential to reduce their kinetic energy barriers. Electrospun nanomaterials possess a unique one‐dimensional structure for outstanding electron and mass transportation, large specific surface area, and the possibilities of flexibility with the porous feature, which are good candidates as efficient electrocatalysts for water splitting. In this review, we focus on the recent research progress on the electrospun nanomaterials‐based electrocatalysts for HER, OER, and overall water splitting reaction. Specifically, the insights of the influence of the electronic modulation and interface engineering of these electrocatalysts on their electrocatalytic activities will be deeply discussed and highlighted. Furthermore, the challenges and development opportunities of the electrospun nanomaterials‐based electrocatalysts for water splitting are featured. Based on the achievements of the significantly enhanced performance from the electronic modulation and interface engineering of these electrocatalysts, full utilization of these materials for practical energy conversion is anticipated.
