AI Technical Summary
Existing γ-Al2O3 and SiO2 supports suffer from poor hydrothermal stability or weak metal-support interactions in the selective hydrogenation of biomass derivatives, leading to rapid catalyst deactivation and low conversion rates, which fail to meet the economic requirements of industrial production.
Using polymethylsilsesquioxane (PMSQ) microspheres as a support, metallic nickel is uniformly loaded through a vacuum freeze-drying process to form a core-shell structured supported nickel-based catalyst. Combined with a specific preparation method, the catalyst is ensured to have both hydrophilic and oleophilic wetting properties and high-temperature stability.
It achieves highly selective and active hydrogenation reactions of biomass derivatives in different reaction media, producing bio-based alcohols such as cyclopentanol and tetrahydrofurfuryl alcohol. It has both broad-spectrum media adaptability and excellent stability, and is suitable for aqueous phase, polar organic solvent phase or non-polar organic solvent phase.
