Ruthenium nanoparticle-containing hydrotalcite catalysts work efficiently for the conversion of biomass-derived HMF into liquid fuel 2,5-dimethylfuran.
An efficient catalytic process for the selective conversion of biomassderived 5-hydroxymethylfurfural (HMF) to high quality liquid fuel 2,5-dimethylfuran (DMF) was achieved over Ru nanoparticles dispersed on NaY zeolite. The structural and morphological features of the catalysts were studied by using various physicochemical characterization techniques. HMF conversion of 100 mol % with 78 mol % DMF yield was achieved using 2 wt %Ru−NaY catalyst in a short duration of the reaction. This catalyst displayed excellent recyclability without any loss in activity when it was used for five times. The study clearly showed that well-dispersed Ru nanoparticles are highly active and selective for the conversion of HMF to DMF. The reaction pathway for the conversion of HMF to DMF was explored by monitoring the reaction intermediates at different stages and intervals of the reaction.
Highly dispersed Ru nanoparticles supported on N-doped mesoporous carbon demonstrated an admirable catalytic activity in catalytic transfer hydrogenation of 5-hydroxymethylfurfural to 2,5-dimethylfuran and furfural to 2-methylfuran.
A noble-metal free FeCu based bimetallic catalyst system prepared by facile co-impregnation method was found to be a highly admirable for vapour phase selective hydrogenation of furfural to furfuryl alcohol at ambient pressure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
