A series of self-assembled Pd/CeO2 catalysts were synthesized by a facile one-pot redox method, demonstrating high catalytic performance in hydrogenation of levulinic acid. Under optimized conditions, almost 100% gamma-valerolactone yield was achieved using Pd/CeO2 catalyst with only slight activity loss (ca. 4%) after five continuous runs. Combined with relevant characterization techniques, the superior catalytic hydrogenation performance could be attributed to Pd/CeO2 catalyst with noticeable advantages of high surface area beneficial to the exposure of Pd catalytic active sites and increase electron density of Pd favorable ...
