High surface area ThO2 catalyst and method of preparing it

摘要

A ThO2 catalyst having a high surface area of about 80-125 m2/g is synthesized. The compound is synthesized by simultaneously mixing an aqueous solution of ThNO3(NO3)4.4H2O with an aqueous solution of Na2CO3.H2O, to produce a solution and solid ThOCO3. The solid ThOCO3 is separated from the solution, and then calcined at a temperature of about 225 DEG -300 DEG C. for about 40-55 hours to produce ThO2. The ThO2 catalyst produced includes Na present as a substitutional cation in an amount equal to about 5-10 atom percent.
