摘要：
ZrO2 species with different crystal phases (monoclinic, amorphous and tetragonal) were synthesized and used as supports for Pd -based bifunctional catalysts. ZrO2 species could affect the acidic and basic properties of the catalysts and the dispersion of Pd nanoparticles. The hydrogenolysis of glucose has been performed on the Pd/ZrO2 catalysts. The synergistic effect between Pd nanoparticles and ZrO2 species could catalyze the selective hydrogenolysis of glucose. For example, the highest selectivity of ethanol was obtained on the Pd/t-ZrO2 catalyst, with the value of 39.7%.
