Strain-Rich Pt₃Co Nanocrystal Catalyst

Atomically Locked Strain

Compressive lattice strain is firmly locked within ordered L1₂ intermetallic Pt₃Co nanocrystals via unsteady thermal shock and ultrafast crystallization, shifting the d-band center negatively to optimize oxygen intermediate adsorption and boost Li-O₂ battery catalysis and durability.
