Colloid-Mediated Synthesis of Hierarchically Porous Amorphous Catalyst for Durable Industrial-Scale Water Electrolysis.

ABSTRACT: Efficient and scalable hydrogen production via water electrolysis requires electrode architectures that combine high catalytic activity, effective active-site utilization, and mechanical durability at industrial current densities. However, conventional synthesis routes often produce dense, fragile catalyst layers that limit performance and scalability. Herein, a colloid-mediated electroless plating (CMEP) strategy is reported for the facile fabrication of hierarchically porous, amorphous Fe-NiWB electrodes under ambient conditions. During CMEP, the in situ generation of Fe-W-O colloids suppresses compact layer growth, yielding an open architecture with abundant accessible sites, accelerated mass transfer, and strong substrate anchoring.
