Summary: Co/N-C catalysts prepared by solvothermal crystallization method demonstrate high catalytic activity for the synthesis of 2,5-dimethylfuran. The excellent catalytic activity is attributed to the highly dispersed Co nanoparticles in the porous structure.

Summary: A bimetallic Pt-FeOx/AC catalyst was prepared for the selective hydrogenolysis of HMF to DMF, achieving a high yield of 91%. The addition of FeOx enhanced Pt dispersion and catalytic activity, inhibiting undesired hydrogenation reactions. However, leaching of Fe species led to an increase in ring hydrogenation products.

Summary: This study focuses on the development of sustainable and efficient catalysts for the selective hydrogenation of HMF to HHD using Ru supported on activated biochars. Activated biochars derived from different biomasses show distinct properties, with A(HSw) displaying better trapping and anchoring of Ru nanoparticles, leading to higher catalytic activity.

Summary: In this study, an alloying method was used to introduce Fe species into Ni-Al catalysts to form oxyphilic FeNi alloy, allowing for the selective conversion of HMF to DMF. The results showed that the Ni-Fe-Al alloy reduced the hydrogen adsorption and activation capability, leading to the formation of DHMF and 5-MFA instead of DMF during the hydrogenation of HMF. The FeNi alloy exhibited high affinity for the adsorption and activation of C-OH in DHMF and 5-MFA, promoting their hydrogenolysis to DMF.

Summary: This review article discusses the recent studies on the catalytic conversion of 5-hydroxymethylfurfural (5-HMF) into 2,5-dimethylfuran (2,5-DMF). It presents the latest catalytic materials and their main results in 2,5-DMF production through catalytic hydrogen transfer (CHT) reactions and hydrodeoxygenation (HDO) reactions. The optimized reaction conditions for each catalyst are also discussed. The article also provides future perspectives on the use of CHT and HDO processes for 2,5-DMF production from 5-HMF as a platform molecule in heterogeneous catalysis.

Summary: Recent advances in the transformation of biobased 5-hydroxymethylfurfural to 2,5-dimethylfuran, a potential liquid fuel, have been critically summarized. The highest yields were obtained using bimetallic Cu-Co supported on carbon or Ni supported on mesoporous carbon under specific reaction conditions. The ideal catalyst should have high metal dispersion and some acidity to promote both hydrogenation and hydrogenolysis, while minimizing the formation of byproducts.

Summary: The crystal structure of catalyst support plays a significant role in influencing its surface and electronic properties, thereby affecting catalytic activity. By preparing monoclinic, tetragonal, and mixed phase Co/ZrO2 catalysts, different hydrogenation and hydrogenolysis activities were observed in the conversion of HMF to DMF. The interaction between cobalt and t-ZrO2 resulted in higher hydrogenation activity, while the presence of acid concentration on the surface of Co/m-ZrO2 led to higher efficiency in hydrogenolysis reactions. The combination of high hydrogenation and hydrogenolysis activities in Co/Mix-ZrO2 achieved the highest yield of DMF under mild conditions.

Summary: A CoMo bimetallic catalyst with CoN4 single atom sites and low Co content (0.14 wt%) was developed for the hydrodeoxygenation of 5-Hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF). The catalyst exhibited superior performance compared to previous works and a synergistic effect between Co and Mo sites was disclosed. Mechanistic studies revealed that 5-methyl-2-furaldehyde (MF) was the main reason for the production of 1,2-bis(5-methylfuran-2-yl)ethane (BMF) and the hydro-genolysis of the aldehyde group was the slow step of the reaction. A two-step and one-pot process was exploited based on these insights for higher DMF yield under milder conditions.

Summary: Designing efficient and low-cost catalysts for biomass conversion is important yet challenging. In this study, a non-noble Ni-Mn bifunctional catalyst was developed and found to be economic and efficient for the selective hydrodeoxygenation of biomass-derived 5-hydroxymethylfurfural (5-HMF) to 2,5-dimethylfuran (2,5-DMF). The catalyst exhibited outstanding reusability and achieved high conversion and yield under mild reaction conditions. The addition of Mn enhanced reactivity and shifted the dominant reaction pathway, which was attributed to the synergy of Ni metallic nanoparticles and MnOx Lewis acid sites.

Summary: In this study, Cu-Co/CeOx catalysts were prepared and utilized for the hydrogenolysis of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) via reduction of layered double hydroxide precursors. The formation of CoCe-Vo interface and the spillover effect of hydrogen from Cu species to CoCe-Vo interface were confirmed, and it was demonstrated that the CoCe-Vo interface could activate the C-O bond. The optimized catalyst exhibited high DMF yield and stability in the cycling tests.
