An improved X-ray reactor chamber for the simultaneous structural and catalytic characterization of catalysts
Abstract The construction and the way of working of an improved X-ray reactor chamber (XRK) are described, designed for studies of solid state-gas reactions; a particular area of application is heterogeneous catalysis. By means of the XRK the structural and catalytic properties of Cu-SiO 2 , Ni-SiO 2 , Cu-ZnO-Al 2 O 3 and Si-Cu catalysts were investigated in situ during the stages of reduction, reaction and ageing. The structure of the detected amorphous phase (Cu,Zn)-hydrotalcite was studied by the calculation of the radial atomic distribution function (RDF).
