(a) Cross-sectional SEM image. (b) SAED pattern of hydrothermally synthesized {0001}-faceted NiS nanosheet film. The inset of b depicts the TEM image of the NiS nanosheet film. (c) Direct dissociation of the I2 molecule upon adsorption at the S-vacancy dimer in the direction of (0001) at the NiS(0001) surface. (d) Adsorption configuration of the I atom sitting at the S-vacancy position. Light-blue, yellow and brown represent the Ni, S and I atoms, respectively.
