Summary: A series of carbon nanotube-supported Ni-based catalysts were prepared through a simple impregnation method, showing smaller particle size and better dispersion compared to monometallic Ni/CNT catalyst. The synergistic effect of Ni with Mo led to high activity in hydrogenation of biomass derivatives in aqueous medium. NiMo/CNT bimetallic catalyst exhibited a promotional effect in hydrogenation of furfural to fine chemicals, with potential applications in the food and biomass refining industry.

Summary: In this study, spherical NiMo bimetal catalysts were prepared using a simple wet impregnation method and studied for selective hydrogenation of furfural. The Ni/C-Mo-BTC catalyst showed the highest selectivity of CPL (up to 90%), while the optimal Ni/C-Mo0.4 catalyst could be efficiently applied in five consecutive recycling tests. Water played a key role in the formation of different desired products in the FFA hydrogenation process.

Summary: The study focuses on catalyst deactivation and carbon loss in furfural conversion in the aqueous phase. By synthesizing Cu catalysts with alkali or alkaline earth metal additives, it was found that these additives inhibited condensate formation significantly, likely due to the stabilization effect of important carbocation intermediates. Characterization techniques revealed that the condensates on catalyst surfaces were highly conjugated polymers resulting from the polymerization of furfuryl alcohol.

Summary: In this study, a series of Ni, Cu, Mo, Co bimetallic catalysts supported on carbon nanotubes (CNT) were synthesized and fully investigated for the hydrogenation of biomass-derived furfural (FFA) to cyclopentanol (CPL). Among the catalysts, (15 + 5) wt% NiCu/CNT catalysts showed the highest conversion of FFA and selectivity towards CPL in water and acetal in methanol under mild conditions. The synergistic effect of the NiCu bimetallic catalyst was explained, and the features of the CNT-supported catalysts were investigated. The low cost and simplicity of the catalysts make them a promising candidate for the conversion of biomass-derived FFA to CPL.

Summary: In this study, a one-dimensional metal-organic framework containing Cu (II) and Ni (II) active sites was designed using a N,N'-bis-(4-pyridyl)isophthalamide linker to form MOF 1 [Cu-1/2(L1)(NO3-).DMF] and MOF 2 [Ni(1/2)L1Cl]. The performance of MOF 2 catalyst was evaluated for the hydrogenation of furfural to furfuryl alcohol, and impressive results were obtained with a conversion of FF of 81% and selectivity towards FA of 100%. The structural integrity of MOF 2 was not affected after catalysis, and the catalyst could be reused without significant loss in activity and selectivity. A possible reaction mechanism for the reaction over MOF 2 was proposed.

Summary: This study investigated the synthesis of catalysts with Ni-Fe and Mg-Al layered double hydroxides as precursors. It was found that the presence of Fe in the catalyst affected both the structure and performance of the catalyst, influencing the hydrogenation of furfuryl alcohol and promoting the production of pentanediols.

Summary: The effect of calcination temperature on the electronic structure and the spatial distribution of oxygen vacancies (OV) of anatase TiO2 supported Ni catalysts was studied. High-temperature calcination led to the co-reduction of TiO2 and NiO, forming OV near Ni0 and transferring electrons to Ni0 to fill its D-band with more electrons, forming Nid- species. The Nid- species formed on the surface of Ni/TiO2 were considered as the active site for the selective hydrogenation of furfural to furfuryl alcohol.

Summary: In this study, five types of nano metal oxide supported Ni catalysts were prepared and evaluated for liquid-phase furfural hydrogenation. Among them, Ni/MgO catalyst exhibited superior performance with a high conversion rate of furfural and a high selectivity of furfuryl alcohol. The catalytic characterization results indicated that when MgO was used as the support, a solid solution of NiO-MgO was formed, resulting in highly dispersed amorphous Ni on the support surface, which contributed to the high selectivity of furfuryl alcohol. Additionally, a slight decrease in catalytic activity of Ni/MgO may be attributed to the formation of Mg(OH)2 during cyclic utilization.

Summary: The catalytic transfer hydrogenation of alpha,beta-unsaturated aldehydes using single metal atom catalysts supported on nitrogen-incorporated graphene sheets has gained attention. A Ni-N-3 site in the catalyst was found to be more active in facilitating hydrogen transfer and showed higher chemoselectivity for furfural to furfuryl alcohol. The proposed reaction mechanism could guide the design of single metal atom catalysts for chemoselective hydrogenation reactions.

Summary: Cu-Ni alloy supported on MCM-41 catalysts were developed for the CTH of FFA into FOL, with the 15Cu-15Ni/MCM-41 catalyst showing the best performance. The synergistic effect between Cu and Ni metals, along with moderate hydrogenation capacity of 2-propanol, contribute to the efficient conversion of FFA and high selectivity to FOL.
