Highly dispersed copper nanoparticles supported on Al2O3 are successfully prepared via the facial co-precipitation method. The addition of appropriate amount of ZnO is beneficial to the formation of highly dispersed copper species on the surface of Cu/ZnO/Al2O3 samples. The Cu/ZnO/Al2O3 (4/2/4) catalyst which does not need the reduction pretreatment shows much higher activity compared with those catalysts commonly used for this reaction. A high glycerol conversion (92.5%), with 99.0% selectivity to 1,2-propanediol was obtained under mild reaction conditions (453 K, 3 MPa initial H2 pressure).
Keywords:Cu/Al2O3; Cu/ZnO/Al2O3; glycerol; 1,2-propanediol; hydrogenolysis
