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 synthesis of efficient non-noble metal catalysts is crucial for chemical transformations. In this study, hexagonal close-packed cobalt (HCP-Co) was synthesized through a simple reduction process of beta-Co(OH)(2) nanosheets. HCP-Co exhibited significantly higher catalytic efficiency than its face-centered cubic cobalt (FCC-Co) counterpart, especially in the hydrogenation of the C=C/C=O group. Density functional theory calculations revealed that HCP-Co had stronger adsorption and lower activation energy than FCC-Co, leading to high activity and selectivity. The stability of HCP-Co during the hydrogenation of 5-hydroxymethylfurfural (HMF) was also excellent.

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, 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 study demonstrates an efficient method for the hydrogenolysis of HMF to DMF under mild reaction conditions using Pd nanoparticles supported on N-containing and N-free mesoporous carbon materials, along with formic acid (FA) and hydrogen. It was found that the main role of FA is to shift the dominant reaction pathway from the hydrogenation of the aldehyde group to the hydrogenolysis of the hydroxymethyl group, thereby significantly enhancing the reaction rate. The interaction between Pd2+ species and pyridine-like N atoms was shown to enhance the selective hydrogenolysis of the C-OH bond in the presence of FA, leading to the stabilization of H-.

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: In this paper, a copper-palladium bimetal supported on carbon-doped boron nitride (BCN) catalyst was prepared to improve the selectivity of 5-hydroxymethylfurfural (HMF) hydrodeoxygenation (HDO) to 2,5-dimethylfuran (DMF). The catalyst of 10Cu3Pd/BCN showed remarkable activity with high selectivity (99.2 %) for DMF under the combined action of Cu-Pd alloy and support. Moreover, the packing and dispersion of the alloy particles by the carrier improved the cycling performance of the catalyst. Therefore, the selection of 10Cu3Pd/BCN as a catalyst for HDO has excellent application prospects.

Summary: Hydrothermal carbonization is an effective method to treat sludge, but the high nitrogen content in the sludge hydrochar causes environmental pollution. This study used layered double oxides (LDO) catalysts to catalytically remove nitrogen during hydrothermal carbonization. The LDO catalysts significantly improved nitrogen removal, achieving more than 57.00% at 240 degrees C. Additionally, by adjusting the metal ratio of the catalysts, the acid-base sites could be modified to produce low nitrogen hydrochar.

Summary: A unique nanomaterial platform was developed for trace detection and efficient degradation of triclosan (TCS) using a silver spherical nanoparticle (AgNP)-modified ZnO multipods (ZnO@Ag) template. The ZnO@Ag template demonstrated excellent degradation and detection performance, with TCS degradation up to 92% under UV irradiation at 365 nm and a detection limit as low as 10-9 M. This is the first investigation into the use of ZnO@Ag bimetallic composites for SERS-based detection and UV-assisted degradation of environmental TCS pollutants. The technology was successfully applied to determine antibacterial agents and TCS in distilled or river water, highlighting the advantages of the ZnO@Ag template over conventional detection methods.

Summary: Aluminum sulfate was used as the main accelerator in the investigation of new non-chloride and alkali-free cement accelerators. Acrylic acid, aluminum fluoride, or alkanolamine were employed as regulators to further enhance cement setting. The experimental results showed that the addition of acrylic acid alone decreased the setting time of cement and improved the compressive and flexural strengths of mortar, while the introduction of aluminum fluoride or alkanolamine greatly improved this process. Structural characterizations revealed changes in the coordination polyhedron of Al3+ during the transformation process. This work provides a significant strategy for enhancing the activity of aluminum sulfate in cement setting and contributes to the future development of new non-chloride and alkali-free cement accelerators.

Summary: Microwave (MW) and conventional heating (CH) methods were compared for the synthesis of fuel additives from levulinic acid. Phosphomolybdic acid (PMA) and phosphotungstic acid (PTA)-containing graphitic carbon nitride (GCN) were synthesized and optimized to achieve high yields. MW significantly reduced reaction times and is a more sustainable approach for the synthesis of various fuel additives. Scale-up experiments showed that MW with optimum GCN-PMA achieved higher productivity compared to CH conditions.
