目前，电催化水分解已被认为是解决迫在眉睫的能源危机和环境问题的最有效手段之一。然而，为了提高析氢反应（HER）和析氧反应（OER）半反应的电催化转化效率，通常需要电催化剂来降低其动能垒。电纺丝纳米材料具有独特的一维结构，具有出色的电子和质量输运，大的比表面积，以及多孔特性的灵活性，是水分解的高效电催化剂的良好候选材料。本文综述了近年来电纺丝纳米材料电催化剂在HER、OER和整体水裂解反应中的研究进展。具体而言，将深入讨论和强调这些电催化剂的电子调制和界面工程对其电催化活性的影响。此外，还分析了电纺丝纳米材料基水分解电催化剂面临的挑战和发展机遇。基于这些电催化剂在电子调制和界面工程方面所取得的显著提高性能的成就，人们期待着这些材料在实际能量转换中的充分利用。
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.
