(a) Evolution of the atomic phase fraction content of Co species as a function of temperature, obtained from PXRD Rietveld refinement of the powder patterns presented in Fig. 5[link]. (b) Evolution of the atomic phase fraction obtained from the XANES data using the linear combination fitting method. Panels (c), (d) and (e) compare the atomic fractions obtained from XRD and XANES measurements for Co3O4, CoO and metallic Co, respectively. Injection of H2 to the gas stream is marked by red arrows.
