Gas evolution plays an important role in water electrolysis, as sluggish bubble dynamics lead to blockage of active sites, reduced catalytic performance, and even detachment the catalysts. In this work, we present a strategy fabricate highly rough three-dimensional (3D)-printed Ni (3DPNi) electrodes with ordered flow channel structures, achieving exceptional performance through enhanced transport dynamics. The surfaces enhance hydrophilic aerophobic properties, suppressing coalescence accelerating structures 3DPNi serve efficient channels effectively prevent trapping, facilitating rapid Collectively, these features optimize dynamics, significantly boosting for electrolysis. Computational fluid simulations visual experiments validate improved When coated NiFe-LDH (NiFe-LDH/3DPNi), low overpotential 238 mV is required deliver 100 mA cm-2 OER. overall splitting, NiFe-LDH/3DPNi || Pt plate setup requires cell voltage 1.86 V achieve 1 A demonstrates excellent stability over h at current density, indicating strong potential practical applications.
