Key Points

The aim is to evaluate the performance of starfish-inspired gas-evolving electrode scaffolds for alkaline water electrolysis.
Developed 3D-printed starfish-inspired gas-evolving electrodes.
Assessed electrolysis performance through hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).
Evaluated Faraday efficiency over a sustained operational period.
Achieved approximately 100% Faraday efficiency over 150 hours of operation.
Indicated high operational stability and potential for practical applications in alkaline water electrolysis.

Abstract

for HER and OER, respectively. Moreover, our starfish-inspired GEE sustains ACDs operation with ≈100% Faraday efficiency for over 150 h, demonstrating its potential for practical AWE applications.
