Composition, biomass pine wood

In the present work CcosZro 5O2 was prepared by the following method pine sawdust (wood biomass with the approximate size of 0.63-1.25 mm) was impregnated by solution of Ce and Zr nitrates in the ratio sawdust mixed oxide = 10 1 and the dried resultant system was calcined at 600°C during 4 hours to give, in a direct and simple manner, the material of desirable and predictable porosity, avoiding the use of additional chemicals in the process. The sample obtained with the help of sawdust is indicated as biomorphic. For comparison Ce-Zr oxide of the same composition was prepared by traditional coprecipitation method and calcined in the same conditions.
