Description
Xiaolin Tai and ten co-authors wrote a 2025 study on engineering the layer just beneath a catalyst's surface. In heterogeneous catalysis, the atoms below the surface quietly govern what happens on it. Arranging those buried atoms precisely has been nearly impossible, blocked by complex interactions and poor access.
The team built atomic diffusion pathways in place, guiding foreign atoms into the subsurface of platinum-iron intermetallic particles. Surface energy and adsorbate pull then rearranged them into order. The method produced a family of particles with ruthenium, rhodium, palladium, or silver parked in the subsurface layer. The palladium version kept both ligand and strain effects alive at once, breaking a usual trade-off where a platinum skin kills one to gain the other. Catalytic performance improved accordingly. The work opens subsurface design as a practical craft.
