Physico-Chemical and Catalytic Properties of
Nanocrystalline Heterogeneous Catalysts Pd(Rh)/ZrO2(TiO2)
Prepared in Sub- and Supercritical Water
Abstract
Physical, chemical and catalytic properties of the
nanocrystalline supported catalysts of the composition Pd(Rh)/ZrO2(TiO2)
prepared using sub- and supercritical water are investigated. All the materials
were characterized by X-ray diffraction analysis, BET surface area
measurements, transmission electron microscopy, elemental analysis for C/H/N,
differential thermal analysis. The active metal content on the surface of the
catalysts was also determined. Catalytic activity of Pd(Rh)/ZrO2(TiO2)
catalysts was investigated in a flow rector on the example of CO oxidation
reaction. It is shown, that catalysts prepared in sub- and supercritical water
exhibit new interesting properties compared to the materials synthesized by
traditional techniques.
