Constructing Amorphous‐Crystalline Interfacial Bifunctional Site Island‐Sea Synergy by Morphology Engineering Boosts Alkaline Seawater Hydrogen Evolution

Advanced Science, Journal Year: 2024, Volume and Issue: 11(24)

Published: March 18, 2024

Abstract The development of efficient and durable non‐precious hydrogen evolution reaction (HER) catalysts for scaling up alkaline water/seawater electrolysis is highly desirable but challenging. Amorphous‐crystalline (A‐C) heterostructures have garnered attention due to their unusual atomic arrangements at hetero‐interfaces, exposed active sites, excellent stability. Here, a heterogeneous synthesis strategy constructing A‐C non‐homogeneous interfacial centers electrocatalysts on nanocages presented. Isolated PdCo clusters nanoscale islands in conjunction with Co 3 S 4 A‐C, functioning as bifunctional site “island‐sea” synergy, enable the dynamic confinement design metal atoms, resulting HER catalytic activity durability. hierarchical structure hollow porous nanoclusters, along large surface area multi‐dimensional boundaries defects, provides catalyst abundant centers. Theoretical calculations demonstrate that combination regulates redistribution interface electrons effectively, promoting sluggish water‐dissociation kinetics cluster sites. Additionally, PdCo‐Co heterostructure exhibit outstanding seawater long‐term stability 100 h, which can be powered by commercial silicon solar cells. This finding significantly advances large‐scale production.
