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, Ag/TiO2 materials with different interfacial structures were prepared and used for the photocatalytic conversion of biomass-derived 5-HMF to value-added HMFCA. It was found that low-temperature reduction could enhance the photoinduced charge separation efficiency and the localized surface plasmon resonance effects. The 2.5% Ag/TiO2-LTR showed the highest HMFCA selectivity of 96.7% under visible-light illumination. However, the photocatalytic efficiency decreased significantly when the reduction temperature increased due to the encapsulation of Ag NPs by a thicker TiOx overlay.

Summary: A stable catalyst with Mo-doped Co9S8 nanoparticles anchored on Al2O3 matrix was fabricated, which showed high selectivity and stability in the hydrodeoxygenation of lignin. The Mo-Co9S8 structure demonstrated strong ability in the adsorption and activation of oxygen-containing substrates, enabling effective C-O cleavage and avoiding undesirable hydrogenation reactions. The superior stability and water-resistance were attributed to the anchoring effect of Al2O3 matrix and protection of surface-rich Co9S8 species.

Summary: In this study, a novel method for upgrading biomass-derived phenolic monomers through hydrogen-free hydrodeoxygenation (HDO) was proposed and evaluated. The HDO process was combined with the activation of water and aqueous phase reforming of in situ generated methanol over a nano-porous Ni catalyst, resulting in a one-pot approach with high selectivity of bio-phenol. DFT calculations confirmed the crucial role of the Ni catalyst in activating water and facilitating the subsequent HDO process.
