Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

Droplet, EarlyView.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...
