Characterization of Pt/C Catalyst by Small Angle X-ray Scattering(In Chinese)

Abstract

Pt/C catalyst plays an important role in hydrogen-water isotopic exchange reaction.Small Angle X-ray scattering(SAXS)is applied to investigate the structure of three kinds of Pt nanoparticles which were produced by three processes,Glycol synthesis,Soakage-reducing and Microwave heating.The SAXS analysis of size,shape,surface and the aggregates of primary Pt parti- cles is reported here.Additionally,Transmission Electron Microscope(TEM) measurements also carried out,the results of TEM are in agreement with SAXS conclusions.It is shown that three processes produced different sizes and surface area of Pt aggregations.
