a The deformation charge density analysis of AC-Ir NSs with 4% tensile strain, C-Ir NSs and A-Ir NSs, respectively (isosurface is 0.12 bohr−3, cyan represent charge depletion and yellow represent charge accumulation.). b The dxz+yz+z2 band centers of the active Ir sites for AC-Ir NSs with 4% tensile strain, C-Ir NSs and A-Ir NSs, respectively. Note: ɛd refers to Edxz+yz+z2. c The calculated ∆GH* on AC-Ir NSs with 4% tensile strain, C-Ir NSs and A-Ir NSs respectively. d The dxz+yz+z2 band centers of the active Ir sites and the calculated ∆GH* on AC-Ir NSs with different degrees of lattice expansion.
