As an important biomass resource, γ-valerolactone (GVL) shows considerable potential for applications in biofuel production, organic synthesis, polymer, and food industries. Herein, effective method was presented synthesizing GVL through the catalytic transfer hydrogenation (CTH) of ethyl levulinate (EL) under mild conditions. Using isopropanol as a hydrogen donor, 100% conversion 88.7% yield were achieved over 2%Zr-Beta-7d catalyst at 110 °C 8 h. The acidic sites synthesized Zr-Beta via hydrothermal methods easily adjusted offered high activity selectivity. Lewis (L) acid on zeolite serve active centers EL. Characterization results indicate that amounts L increased with Zr content crystallization time rose, thus enhancing selectivity GVL. Additionally, influences dosage, reaction temperature, performance are studied, well calculations kinetic parameters such rate constants activation energies. retains its after five cycles. current research may present efficient approach EL to
