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.
