Conversion of levulinic acid to γ-valerolactone over Ru/Al2O3-TiO2 catalyst under mild conditions.Novel catalytic material with high catalytic activity and hydrothermal stability plays a key role in the efficient conversion of levulinic acid (LA) to γ-valerolactone (GVL) in water.  Moreover, the catalyst Ru/Al2O3-TiO2 exhibited excellent thermal stability in the test period of time.
