A nanodispersed solid solution based on the Ce0,72Zr0,18Pr0,1O2-δ crystal lattice was synthesized by co-precipitation followed heat treatment. The identification of material carried out X-ray phase analysis, energy dispersive photoelectron spectroscopy, transmission electron microscopy, low-temperature nitrogen adsorption, and gas chromatography. It has been established that is superior in catalytic activity thermal stability to CeO2 Ce0,8Zr0,2O2 due doping with Pr+3 ions.
The paper considers the structural and physical characteristics of carriers based on ceramic highly porous block materials a cellular structure, which provide sorption-filtering properties contact elements. Methods for determining external specific volumetric surface, gas-dynamic resistance gas permeability are described. Their interrelation optimal combination with operational sorbent filters in processes capturing volatile compounds iodine cesium streams is shown. results obtained can be...
