In situ x-ray diffraction studies of carbon oxydation catalysed by Mo, Co, Ni and their mixtures

Research output: Contribution to journalConference article

Abstract

Direct in-situ observation of the metal catalyzed gasification of graphite under the electron microscope has been reported. Information about the microstructure and nature of the phases using ex-situ X-ray diffraction (XRD) and electron microscopy has been presented (3-6). Ex-situ microstructure observation, however, gives rise to uncertainity. In this report on in-situ X-ray diffraction. Experiments indicate that (a) The bulk phases observed under Mo, Ni and Co catalysed active carbon gasification by oxygen were MoO3, NiO and Co3O4, respectively. (b) In the case of Ni and Co, the mode of addition of the catalyst (impregnation of mechanical mixing) is irrelevant. XRD patterns and kinetic behaviour are the same.
