摘要：

This study investigates the catalytic transfer hydrogenation (CTH) of methyl levulinate (ML) into gamma-valerolactone (GVL) using mixed metal oxides derived from metal-organic frameworks (MOFs) under continuous flow conditions. A series of MOF-derived Al2O3-ZrO2/C catalysts with different Al/Zr molar ratios were investigated, revealing a synergistic effect that significantly enhances catalytic efficiency. Physico-chemical characterization demonstrates that the incorporation of aluminum into zirconium dioxide increases the surface area as well as the presence of catalytically active acid and basic sites, which are essential for the efficient transfer hydrogenation of ML into GVL. Al2O3-ZrO2/C (1 : 1) exhibited the highest ML conversion rate (80%) and GVL yield (72%) at 200 degrees C within 30 minutes. The study also emphasizes the critical role of reaction parameters in maximizing GVL production. The stability and reusability of the Al2O3-ZrO2/C (1 : 1) catalyst, following appropriate thermal treatment, were also assessed.
