Solid-state kinetics from time-resolved in situ XAFS investigations: Reduction and oxidation of molybdenum oxides

Abstract

The reduction of MoO3 with hydrogen was studied by in situ X-ray absorption spectroscopy. The experiments performed focused on elucidating phase composition and evolution with time under isothermal reduction conditions. From temperature programmed experiments short-range structural details about the early stage of the reduction were obtained.
