Preparation and Characterization of Dispersed Rh2O3 on Tetragonal ZrO2.

Abstract Samples of well-dispersed hexagonal Rh 2 O 3 on tetragonal ZrO 2 have been prepared by the code composition of the nitrates at 900°C. A comparison of the stability towards reduction of the bulk and dispersed Rh 2 O 3 products demonstrates the influence of an interaction between the dispersed metal oxide and the support.
