Abstract

The compositions of multicomponent boehmite suspensions in the pH range of the dispersion medium from 1.5 to 5.4 and methods of stabilizing cerium-and platinum-containing suspensions and application on a block cordierite support were investigated. The optimum conditions of preparing the suspensions and single-stage production of highly porous, strong, and uniform coatings of the Pt-CeO2-γ-Al2O3 system with a high yield and specific surface area of 150–170 m2/g were established.
