“…For Cu–Pt@TMS and Cu/TMS catalysts, a rapid increase in band density of the CO stretching vibration (1720 cm –1 ) and ν (CC) (1474 cm –1 ) and furan ring breath (1578 cm –1 ) were observed along with introduction of FFL for 20 min (Figures a and S14). − In the case of Pt/TMS, only the band density of the CO bond was observed, while the IR signals of ν (CC) and furan ring breath were not detected, demonstrating the intense chemical adsorption of the furan ring on the Pt surfaces (Figure b). The aromatic ring breath and ν (CC) would disappear if furan rings have strong chemical adsorption on the metal surface, whereas furan rings without adsorption and an unconstrained state would produce IR signals .…”

Designing optimal heterogeneous metal hydrogenation catalysts for biomass conversion with simultaneously high activity and selectivity is a significant but challenging topic. Herein, we report a modularized hydrogenation mode with hydrogen dissociation and substrate activation on different sites (e.g., Pt and Cu), where Pt nanoclusters are responsible for H2 dissociation and Cu nanoparticles act as the active center for further substrate activation. Specifically, TS-1 zeolite@mesoporous silica with a core–shell structure was fabricated, in which the Pt and Cu species are confined within micropores and mesopores, respectively. Such configurations allow facile dissociation of H2 on Pt sites, followed by the migration of spilled-over hydrogen atoms to the Cu sites where the adsorbed substrates are activated for catalytic hydrogenation. This synergy yields an efficient furfural hydrogenation system with a high turnover frequency (32.8 h–1) and a remarkable furfuryl alcohol selectivity (>99.6%). The modularizing strategy opens up an innovative pathway for fabrication of hydrogenation catalysts with outstanding activity and high selectivity.

Biomass is one of the highly abundant renewable resources available that can be converted into several high-value-added products, including chemicals, biofuels, and advanced materials. To achieve net-zero emissions and improve biomass application, researchers around the world have recently focused on expanding biomass processing techniques to value-added products with the eventual goal of industrializing some of the products. In this review, we summarize lignocellulosic biomass derived furfural (FA) and its subsequent hydrogenation to furfuryl alcohol (FAL). This work reviews the various types of hydrogenation catalysts and their utility in the production of value-added products from FA. There will be an increase in the demand for selective catalysts and process technologies, as well as an increase in the challenges during valorization, as the usage of biomass to achieve carbon neutrality increases. The review aims to provide a concise overview of the advancements in this field and the potential for sustainable FAL production. In this paper, we present a simple strategy for selecting catalyst systems and associated process parameters that facilitate the highly efficient and selective valorization of FA to chemicals or fuel (bioadditives) for industrial use.

The liquid–liquid equilibrium (LLE) data of water + furfuryl alcohol + trichloromethane /methyl isopropyl ketone were determined at 303.2, 313.2, and 323.2 K under 101.3 kPa. The distribution coefficient (D) and separation factor (S) were evaluated for the separation effect of solvents. The nonrandom two-liquid and universal quasichemical models were used to correlate the experimental LLE data and obtain the binary interaction parameters. Meanwhile, the root mean square deviations and absolute average deviation of the two models did not exceed 0.0094 and 0.0066, respectively, which shows that the experimental LLE data can be accurately correlated through the two models. GUI-MATLAB was used to verify the consistency between the LLE data and the calculated binary interaction parameters. σ-Profiles were used to analyze the interaction between the molecules of each substance, further confirming the accuracy of the experimental results.
