Interfacial Oxygen Spillover Between Ru Single-Atom and Ni Cluster in Efficient Water Electrolysis.
The sluggish oxygen evolution reaction (OER) remains a major kinetic bottleneck limiting the efficiency of alkaline water electrolysis, largely owing to the intrinsic scaling relationship among oxygen-containing intermediates on conventional single active sites. Here, a Ru single-atom/Ni cluster interfacial catalyst su...
