title: Temperature-resolved in situ X-ray absorption spectroscopic study on the reduction of nanostructured Fe(2)O(3) within the pore system of mesoporous carbon CMK-1.
abstract: Results of in situ X-ray absorption spectroscopy experiments on the reduction of thin-layered nanostructured X-ray amorphous iron(III) oxides inside the pore system of mesoporous carbon CMK-1 are presented. These in situ measurements were carried out using 4% hydrogen in nitrogen as reduction gas over a 300-1000 K temperature range. The thermochemical behaviour of the nanostructured materials was compared with that of the bulk phases. The spectra series examined by factor analysis gave a good insight into the reduction products of iron oxide nanoparticles occurring in mesoporous carbon CMK-1.
