摘要： 电解水制氢被视为是实现“双碳”目标的关键技术之一，但仍然存在气体粘附电极表面导致电极活性降低的问题。如何快速驱离电极表面气泡，释放有效活性面积，是提升电解水产氢效率的关键。本实验教学设计针对综合电化学、界面化学、热力学和动力学等专业知识，结合界面化学前沿研究领域和传统电化学理论，通过设计构筑具有各向异性微结构的超浸润镍电极表面，降低气泡在电极表面粘附力的同时，研究引导气泡在电极表面各向异性传输的电化学规律及机理，实现气泡的快速脱离，以实现高效产氢。本实验教学设计注重学科交叉融合，科教融通引导学生逐步思考、认知、分析、分解和解决复杂问题，激发学生的学习和科学研究兴趣，提升学生的创新思维和创新能力。

Abstract: Hydrogen production via water electrolysis is a pivotal technology for achieving the “dual carbon” goals (carbon neutrality and peak carbon emissions). However, persistent challenges include gas bubble adhesion on electrode surfaces, which reduces catalytic activity. Rapid bubble detachment to expose active sites is critical for enhancing electrolytic hydrogen production efficiency. This experimental teaching module integrates multidisciplinary knowledge (electrochemistry, interfacial chemistry, thermodynamics, and kinetics) by combining frontier interfacial chemistry research with classical electrochemical theory. Specifically, it designs a superwetting nickel electrode with anisotropic microstructures to reduce bubble adhesion forces while investigating the electrochemical mechanisms governing anisotropic bubble transport. The goal is to achieve rapid bubble release for efficient hydrogen evolution. The module emphasizes interdisciplinary synergy and pedagogical integration, guiding students through systematic problem-solving—from conceptualization and analysis to innovation—to cultivate scientific curiosity, critical thinking, and innovative capacity.
