Ni/Hierarchical Zeolites Derived from Zeolites@Layered Double Hydroxides (LDHs) Composites for Furfural Hydrogenation

Abstract

Furfural hydrogenation is one of the most important reactions for the transformation of biomass-derived resources into high value-added chemicals. To achieve a highly efficient catalytic activity of the reaction, catalysts with a high dispersion of metal nanoparticles (NPs) on solid supports are required. However, the development of highly efficient and stable catalysts is still challenging. Herein, the highly dispersed nickel nanoparticles (Ni NPs) supported on the hierarchical ZSM-5 nanosheets (Z5-NS) derived from the hierarchical ZSM-5 nanosheets@NiAl-layered double hydroxides (LDHs) composites were successfully fabricated. Remarkably, the fabricated Z5-NS/Ni catalyst exhibited a high furfural conversion of 85 % with a yield of furfuryl alcohol of 60 %. This work illustrates the fabrication of highly metal dispersed on solid supports with high metal loading, which can enhance the catalytic performances in the hydrogenation of biomass-derived compounds.
