Efficient bubble/precipitate traffic enables stable seawater reduction electrocatalysis at industrial-level current densities.

Seawater electroreduction is attractive for future H production and intermittent energy storage, which has been hindered by aggressive Mg/Ca precipitation at cathodes and consequent poor stability. Here we present a vital microscopic bubble/precipitate traffic system (MBPTS) by constructing honeycomb-type 3D cathodes for robust anti-precipitation seawater reduction (SR), which massively/uniformly release small-sized H bubbles to almost every corner of the cathode to repel Mg/Ca precipitates without a break. Noticeably, the optimal cathode with built-in MBPTS not only enables state-of-the-art alkaline SR performance (1000-h stable operation at -1 A cm) but also is highly specialized in catalytically splitting natural seawater into H with the greatest anti-precipitation ability.
