Electrocatalysis is considered promising in renewable energy conversion and storage, yet numerous efforts rely on catalyst design to advance catalytic activity. Herein, a hydrodynamic single-particle electrocatalysis methodology developed by integrating collision electrochemistry microfluidics improve the activity of an system. As proof-of-concept, hydrogen evolution reaction (HER) electrocatalyzed individual palladium nanoparticles (Pd NPs), with development microchannel-based ultramicroelectrodes. The controlled laminar flow enables precise delivery Pd NPs electrode–electrolyte interface one one. Compared diffusion condition, improves number active sites given electrode 2 orders magnitude. Furthermore, forced convection enhancement proton mass transport, thereby increasing electrocatalytic each single NP. It turns out that improvement transport increases rate HER at NPs, thus phase transition without requiring high overpotential. This study provides new avenues for enhancing altering operating conditions, beyond material limitations.
