Tuning surface-active sites of Ru catalysts for the selective deoxygenation of lignin monomers to fuels and chemicals

引用

Science China Chemistry 2025年

作者： Rizky Gilang Kurniawan Jongho Choi Neha Karanwal Seung Min Kim Seok Ki Kim Deepak Verma Jaehoon Kim School of Chemical engineering Sungkyunkwan University School of Mechanical engineering Sungkyunkwan University SKKU advanced Institute of nanotechnology (SAINT) Sungkyunkwan University Institute of advanced Composite materials Korea Institute of Science and Technology Department of Chemical engineering Ajou University

Cycloalkanes and cyclohexanols find diverse applications, including sustainable aviation fuel, fuel additives, and value-added chemicals. These compounds can be produced via complete or selective hydrodeoxygenation（HDO） of lignin-derived phenolic monomers. In this study, a urea-assisted method was employed to control the size of Ru nanoparticles（NPs） and tune the surfaceactive sites on Ru metal supported on CNx. By adjusting the Ru-to-urea molar ratio, both the size of Ru NPs and the metallic-tooxide ratio of Ru were controlled, along with the incorporation of N atoms into the RuO2surface coordination. In the absence of urea, the Ru/CNx（1:0） catalyst, containing 4.8 nm Ru NPs, achieved complete HDO of 4-propyl guaiacol to n-propyl cyclohexane through ring saturation, followed by hydro-demethoxylation of the C–OCH3group, and hydrogenolysis of the –OH group, with a 97.0% yield at an initial H2pressure of 1.5 MPa, 200 °C, and 20 h in water. The final hydrogenolysis step was inhibited over the urea-assisted catalysts. The Ru/CNx（1:8） catalyst, containing 3.1 nm Ru NPs, achieved a maximum selectivity of 67.6% for n-propyl cyclohexanol, along with complete conversion of 4-propyl guaiacol. Similar trends were observed in the product distribution when upgrading reductive catalytic fractionation bio-oil over Ru/CNx（1:0） and Ru/CNx（1:8）.

Highly selective [4+4] cross-photodimerization of(4a-azonia)anthracenes driven by confinement of D-A hetero-guest pair in cucurbit[10]uril host

引用

Chinese Chemical Letters 2025年第03期 291-294页

作者： Xianchen Hu Junli Yang Fang Gao Zhiyong Zhao Simin Liu School of Chemistry and Chemical engineering Wuhan University of Science and Technology The State Key Laboratory of Refractories and Metallurgy Institute of Advanced Materials and NanotechnologyWuhan University of Science and Technology

The cross-photodimerization often comes with the formation of undesired and competitive homophotodimer as side products. Herein, we report a series of highly selective [4 + 4] cross-photodimerization between anthracene and 4a-azoniaanthracene derivatives within a cucurbit[10]uril(CB[10]) host in water. Heteroternary inclusion complexes were formed through encapsulation of donor(D1-D2, anthracene derivative) and acceptor(A1-A3, 4a-azoniaanthracene derivatives) pairs in CB[10]. In the presence of CB[10](1.0 equiv.), the [4 + 4] cross-photodimerization between D1 and A1/A2/A3 efficiently gave a single racemic cross-photodimer. Furthermore, the cross-photodimerization between 9-substituted anthracene D2 and A1/A3 was catalyzed by CB[10](0.1 equiv.) to quantitatively yield a cross-photodimer with high regioselectivity. Efficient formation of selective cross-photodimers could be attributed to the exclusive encapsulation of D-A hetero-guest pairs in CB[10] and the confinement effect of the CB[10] host cavity. Our study further proves host–guest complexation as a powerful strategy for cross-cycloaddition reactions with high efficiency.
