[hal-01053703] Multiple and antagonistic effects of water on intrinsic physical properties of model Fischer-Tropsch cobalt catalysts evidenced with in situ X-ray diffraction

Direct evidence for cobalt oxidation under water treatment at 230 °C was revealed with in situ XRD Oxidation kinetics was proved to be particle size dependent Resulting Co3O4 showed a firmly smaller coherent domain size than the initial calcined catalyst Several physical phenomena were proposed to occur during cobalt oxidation by water
