    Abstract

    The reaction of H2S with NiO(100) has been studied by polarization-dependent surface EXAFS. The results evidence reduction of the selvedge to form a Ni raft having S in four-fold sites with a S-Ni bond length of 2.21±0.02Å. The Ni-Ni in-plane distance is 2.77±0.09Å, representing a 6±4% contraction compared to that in NiO(100).
