Highly Stabilized and Accessible Sub-Nanometer RuBi Heteroclusters Drive Efficient Alkaline Hydrogen Evolution.
Controlling the size and interfacial structure of bimetallic hetero-clusters below two nanometers represents a key challenge in catalyst design due to their thermodynamic tendency to undergo sintering and phase segregation. This work presents a dual spatial confinement strategy to synthesize uniformly dispersed, sub-na...
