The use of lignocellulosic biomass to produce renewable and sustainable chemicals and fuels has received considerable attention. Among the various biomass-derived chemicals, levulinic acid (LA) is considered an important platform chemical because it can be transformed to γ-valerolactone (GVL) via hydrogenation, and GVL can be further converted to 1,4-pentanediol (1,4- PDO) via ring opening and hydrogenation. Here, we have demonstrated the one-pot, direct conversion of LA to 1,4-PDO over a trimetallic Zn- promoted Cu–Ni alloy nanoparticles on H-ZSM-5. Under mild reaction conditions at 130 °C and a H2 pressure of 2.5 MPa for 6 h in an aqueous medium, complete conversion of LA to high-yield 1,4-PDO (93.4%) was achieved. The presence of the Zn promoter effectively suppressed the growth of the Cu−Ni alloy nanoparticles on the surface of H-ZSM-5. Due to mild reaction condition, the coke formation and metal leaching were suppressed. |
