Tuning the amount of Sn0 around Ru to promote hydrodeoxygenation of furfural
2-methylfuran (2-MF) is a high-performance gasoline additive due to its high-octane value and good explosion resistance. In this study, cerium tin oxide solid solutions were prepared by a co-precipitation method. The selectivity of 2-MF and the conversion of furfural significantly improved after doping CeO2 with SnO2. 95 % yield of 2-MF was obtained on 5 %Ru/Ce0.975Sn0.025O2, compared to only 40 % yield on 5 %Ru/CeO2. The reaction rate of furfural over 5 %Ru/Ce0.975Sn0.025O2 was 4.9 times higher than that with 5 %Ru/CeO2. Characterizations show an increased concentration of SnO2 around Ru, and the ratio of Ruδ+/Ru reaches a maximum on 5 %Ru/Ce0.975Sn0.025O2. The binding energy shift of Ru0, Sn0, O, and Ce3+ indicates that the introduction of Sn plays an important role in regulating the interface between Ru and CeO2. The increase of Ruδ+/Ru ratio benefits the hydrodeoxygenation of furfural and contributes to the high yield of 2-MF. This study provides a highly active catalyst for the hydrodeoxygenation of furfural.
期刊介绍：
Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications.
Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
