Summary: A high-efficiency nickel-iron bimetallic catalyst with excellent hydrogenation performance and stability was synthesized. The introduction of Fe element formed a protective NiFe2O4 layer on the catalyst surface, enhancing hydrogen adsorption capacity and resistance to oxidation. The introduction of Na element further improved the purity of the catalyst and the interaction between Ni and Fe, leading to enhanced hydrogenation performance. The reaction mechanism was systematically investigated using density functional theory (DFT) calculations.

Summary: Selective aqueous hydrogenation of furfurals to cyclopentanones is achieved by using Ni/Nb2O5 catalysts with different calcination temperatures. The catalytic performance is remarkably enhanced by the reducible NbOx species and water solvent, resulting in a high cyclopentanone yield (>92%). The interaction between NbOx species and Ni sites, as well as the H2O-mediated effect, promotes furfural adsorption and active hydrogen transfer, facilitating the aqueous hydrogenation-rearrangement process.

Summary: The electrocatalytic reduction of furfural for the synthesis of 2-methylfuran was investigated using a carbon-paper-supported Ni-Cu bimetallic material as a catalytic electrode. The presence of Ni remarkably enhances the activity of the Cu electrode, while Cu plays a basic role in the generation of 2-methylfuran. A low pH value is more favorable for the generation of 2-methylfuran than for the formation of furfuryl alcohol. Optimization of Ni2+ concentration in the electrolyte leads to the highest Faradaic efficiency and production rate of 2-methylfuran.

Summary: In this study, selective conversion of furfural into 2-MTHF was achieved using Zn doped Co/NC catalysts. The catalyst with trace Zn dopant exhibited the best performance due to the improved catalytic activity through the presence of Zn in both the carbon support and Co nanoparticles. Theoretical calculations and experimental results demonstrated that the doping of Zn enhanced the dissociation of hydrogen and broke the C-OH bond of FOL, resulting in higher activity for hydrodeoxygenation reactions.

Summary: This study systematically investigated the catalytic transformation of furfural to furfuryl alcohol and 2-methylfuran without the need for hydrogen supply using bimetallic NiCuAl and CoCuAl catalysts. The bimetallic catalysts showed higher yields and selectivity compared to monometallic CuAl and NiAl catalysts, attributed to the stronger Lewis acidic centers on their surfaces.

Summary: The study successfully prepared well-defined Cu nanoparticles encapsulated within titanium silicalite-1 (TS-1) by an in situ encapsulation approach, showing enhanced activity and selectivity for the selective hydrogenation of furfural to furfuryl alcohol. The Na-Cu@TS-1 catalyst exhibited high turnover frequency value and effective suppression of metal aggregation and leaching during catalysis due to the confined environment of the zeolite and electronic interaction between encapsulated Cu nanoparticles and Ti species. Na species in the catalyst not only modulate the acid/base property of the zeolite and suppress side reactions, but also facilitate the FFL hydrogenation by inducing an electronic-rich state in the encapsulated Cu species.

Summary: Furfural, derived from raw agricultural materials, has limited market volume due to its mono-functional furan structure. However, exploration of new catalytic technologies to transform furfural into versatile bifunctional monomers may open up furfural-based biomass utilization and reduce concerns about carbon source scarcity. Development of bifunctional monomers from the furfural platform can potentially boost furfural-based hemicellulose utilization.
