Abstract
A method for making a solid material which is useful as a heterogeneous catalyst including the steps of: forming at least one copper oxide suspension comprising solid particles of copper oxide in a liquid; forming at least one carrier suspension comprising solid particles of a carrier material in a liquid; combining the copper oxide suspension and the carrier suspension; subjecting the combined suspensions to mechanical energy; separating the suspension liquid from the solid particles in the combined suspension; and subjecting the solid material to a thermal decomposition step. A catalyst made by the method has a BET surface area greater than 150 m2/g, a particle size distribution in which D50 is in the range from 25-35 μm, and wherein the D50 after 60 minutes ultrasound treatment is at least 30% of the original value.
