Abstract
To provide a mesoporous cerium oxide loaded PdCu nanoparticle catalyst and a preparing method thereof, as well as a method for preparing enols using the same, and enols.SOLUTION: Melamine and phthalaldehyde are subjected to an aldehyde-amine condensation polymerization reaction to obtain a porous organic polymer template material, then PdCu alloy nanoparticles and a cerium salt precursor are filled in pores of the porous organic polymer template material, and are calcined to remove a template agent to obtain a mesoporous cerium oxide loaded PdCu nanoparticle catalyst. The catalyst can be used for catalyzing selective hydrogenation of alkynol to prepare enols, the conversion rate of alkynol can reach up to 100%, the selectivity of enols is higher than 99%, and the catalyst can be stably applied for at least five times.SELECTED DRAWING: Figure 1
