Bifunctional Zr‐MgAl Layered Double Hydroxide Catalyst for Sustainable Transfer Hydrogenation of Ethyl Levulinate to γ‐Valerolactone

Year: 2024

Type: article

Abstract: A highly versatile and efficient Zr‐MgAl layered double hydroxide (LDH) catalyst has been developed via coprecipitation technique for the transfer hydrogenation of levulinic acid/ester to high‐value γ‐valerolactone (GVL). Detailed state of the art characterizations of the as‐synthesized catalysts involving the structural, compositional, morphological, and surface area analysis were carried out to determine the relation between the physicochemical features and the catalytic activity. The proposed reaction protocol has been optimized by altering various reaction parameters, such as catalyst amount, temperature, time, and different hydrogen sources to obtain the maximum yield of GVL. In addition, kinetic studies were performed to gain deep insights into the role of Zr in catalytic activity, reaction kinetics, and the activation energy of the thermocatalytic process. The synthesis of GVL from renewable biomass resources promotes circular economy and carbon neutrality, paving the way for future research towards the sustainable production of green solvents.
