Abstract:电解水制氢是一种环保、简便且易于操控的制氢技术。工业化电解水制氢通常在高电流密度下进行，在制氢过程中会产生大量气泡，而气泡在电极表面聚集粘附会覆盖大量活性位点，导致电解水效率降低。因此，调控气体扩散行为对于工业电解水应用来说至关重要。近年来，超浸润材料因为其独特的润湿性能而备受关注。通过控制催化剂表面的化学组成和多尺度微纳米结构可以构建出超浸润界面材料。此类材料具有超亲水/超疏气的界面结构，有助于水相电解液的有效浸润和原位生成气泡的快速释放，从而提升催化剂的水电解性能。系统介绍了2014年至2023年期间报道的部分具有超亲水/超疏气界面结构的电解水催化剂的现状，概述其材料的合成设计策略和水电解催化性能，并对超浸润水电解催化剂的研究现状、面临的挑战和应用前景进行了总结和展望。
