Electricity storage in biofuels: selective electrocatalytic reduction of levulinic acid to valeric acid or γ-valerolactone.
Herein, we report an effective approach to electricity storage in biofuels by selective electrocatalytic reduction of levulinic acid (LA) to high-energy-density valeric acid (VA) or γ-valerolactone (gVL) on a non-precious Pb electrode in a single-polymer electrolyte membrane electrocatalytic (flow) cell reactor with a very high yield of VA (>90 %), a high Faradaic efficiency (>86 %), promising ...
متن کاملHigh performing and stable supported nano-alloys for the catalytic hydrogenation of levulinic acid to γ-valerolactone
The catalytic hydrogenation of levulinic acid, a key platform molecule in many biorefinery schemes, into γ-valerolactone is considered as one of the pivotal reactions to convert lignocellulose-based biomass into renewable fuels and chemicals. Here we report on the development of highly active, selective and stable supported metal catalysts for this reaction and on the beneficial effects of meta...
متن کاملLiquid-phase catalytic transfer hydrogenation and cyclization of levulinic acid and its esters to γ-valerolactone over metal oxide catalysts.
Levulinic acid and its esters are converted to γ-valerolactone over metal oxide catalysts by catalytic transfer hydrogenation via the Meerwein-Ponndorf-Verley reaction.
متن کاملConversion of Levulinic Acid to γ-Valerolactone over Few-Layer Graphene-Supported Ruthenium Catalysts
Few-layer graphene (FLG) supported ruthenium nanoparticle catalysts were synthesized and used for the hydrogenation of levulinic acid (LA), one of the “top 10” biomass platform molecules derived from carbohydrates. FLG-supported ruthenium catalyst showed 99.7% conversion and 100% selectivity toward γ-valerolactone (GVL) at room temperature in a batch reactor under high-pressure hydrogen. This c...
متن کاملZrO2 Is Preferred over TiO2 as Support for the Ru-Catalyzed Hydrogenation of Levulinic Acid to γ‐Valerolactone
Catalyst stability in the liquid phase under polar conditions, typically required for the catalytic conversion of renewable platform molecules, is a major concern but has been only sparsely studied. Here, the activity, selectivity, and stability of Ru-based catalysts supported on TiO2, ZrO2, and C in the conversion of levulinic acid (LA) to γ-valerolactone (GVL) has been studied at 30 bar of H2...
