Abstract

Abstract: Anew method for determining the specific interface between different phases in a multi-phase system was recommended and as examples a group of SMSI catalyst Rh/TiO₂was tested.The method,which is based on the calculation of correlation function and electron density fluctuations, was started from the intensity data collected on a rotating-anode X-ray diffraction system. The data were used to calculate the correlation function γ(0) value and the specific interface in multi-phase system using formulas given by Brumberger,et al.The results were valuable for chemists to explain the experiments in catalysis research work such as SMSI catalysis study and so on.

Key words: X-ray, Small angle scattering, Interface in multi-phase system
