A Ni/SiO2 catalyst is found to be effective for the hydrogenation of levulinic acid to yield γ-valerolactone with a quantitative yield in vapour phase conditions at atmospheric pressure without any additives.
Ni nanoparticles supported on various mesoporous silicas with 2D (COK-12) and 3D architectures (KIT-6 and SBA-16) exhibited superior catalytic performance in the vapor-phase hydrocyclization of biomass-derived levulinic acid at atmospheric 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.
