3D Atomic Structure Analysis of NiPt-SP Nanocatalysts at the Single-Atom Level

Caption

High-resolution atomic-level analysis revealed a total of 1,534 atoms (591 Ni and 943 Pt) within the NiPt-SP nanocatalyst. Local atomic arrangement analysis demonstrated that a significant portion of atoms within the crystal grains conform to the Ni3Pt5 intermetallic phase, providing direct evidence of atomic ordering within the NiPt-SP nanoparticles.
