Abstract
Our investigation has aimed to identify the process involved in the H2S - ZnO interaction by in-situ X-ray absorption spectroscopy at the sulphur edge. Time resolved XANES show a progression from chemisorbed H2S to ZnS and in-situ S K-edge EXAFS sveal an intermediate phase containing a S - Zn distance of 2.71 Å. NiO proceeds by a similar pathway after activation at 100°C.
