A hydrophobic palladium/metal organic framework (MOF) material, which is a solid catalyst material obtained by taking a porous MOF as a carrier, introducing elementary palladium by means of an immersion-reduction method, and performing polydimethylsiloxane coating layer processing. A method which uses hydrophobic palladium/MOF material to selectively catalyze hexoses to prepare 2,5-dimethylfuran comprises: dissolving a hexose into an alcohol; using the hydrophobic palladium/MOF material as a catalyst and polymethylhydrosiloxane as a hydrogen donor, reacting at 70 to 130° C. for 0.25 to 12 h under the action of an acidic additive; the concentration of the hexose in the alcohol is 0.2 to 10 wt %, and the total amount of Pd contained in the hydrophobic palladium/MOF material relative to a hexose is 0.1 to 5 mol %. The hydrophobic palladium/MOF material has a stable structure, and under the same conditions, has a catalyzing efficiency which is significantly higher than that of commercially available palladium on carbon and common palladium/MOF materials.

The present invention describes polymer compositions that have enhanced properties as oxygen barriers, as well as manufacturing methods for such oxygen-scavenging polymers and devices composed of such oxygen-scavenging polymers. These oxygen-scavenging polymers offer several benefits over existing materials, including a reduced ability for oxygen and carbon dioxide to permeate the polymer, reduced foaming of beverages stored in containers composed of the polymers, improved moisture absorption, and increased anti-bacterial/anti-fungal properties.
