摘要： Herein, a Ni/Ru bimetallic ordered mesoporous carbon (Ni/Ru@WOMC) was prepared through solvent evapo-ration induced self-assembly (EISA) method with walnut shell organosolv lignin as carbon precursor and Ni2+ as crosslinking agent followed by impregnating small amount of Ru, where the mass ratio of Ni/Ru was about 10:1. The resulting material showed superior catalytic activity on hydrogenation of levulinic acid (LA) to gamma-valer-olactone (GVL). A nearly 100 % GVL yield could be obtained in 2-propanol solvent under mild conditions at a low reaction temperature of 80 degrees C in 4 h reaction time. The Ni/Ru@WOMC catalyst could be used at least 5 times without obvious loss of its catalytic performance, which can be ascribed to the confinement effect provided by their ordered mesoporous structure. This successful development of Ni/Ru@WOMC in the hydrogenation of LA to GVL opens up new opportunities for the catalytic application of lignin derived functionalized ordered mes-oporous carbon in biomass transformation reactions.
