Abstract

Ru nanoparticles (NPs) supported on CeO2−Mg(OH)2 composite nanosheets, donated as Ru/CeO2−Mg(OH)2, are developed as the highly active catalyst for selective hydrogenation of furfural to furfuryl alcohol. Characterization results demonstrate that Ru NPs are adsorbed on the surface of the polyhedra of CeO2, which are scattered on the surface of the thin Mg(OH)2 nanosheets. Ru/CeO2−Mg(OH)2-0.2 achieves 92.6% conversion of furfural and 96.3% selectivity to furfuryl alcohol. Ru/CeO2−Mg(OH)2-0.2 retains high activity after six cycles, due to the introduction of CeO2 to form composite support that effectively prevents the leaching of Ru NPs. The strong metal–support interaction (SMSI) between Ru NPs and the CeO2−Mg(OH)2 composite support can tune the electronic structure of Ru NPs, which facilitates the H2 activation. Moreover, the CeO2−Mg(OH)2 interface exhibits specific adsorption of C=O bonds compared to the CeO2 alone. The composite-supported nanoparticles provide a valuable strategy for constructing highly efficient hydrogenation catalysts.
