Highly Efficient CuCoLa Catalyst for the Direct Hydrogenation of Furfural to Pentanediols
The direct conversion of furfural (FA) from biomass to pentanediols (PeDs), including 1,2-PeD and 1,5-PeD, is important for replacing fossil resources and developing bio-based polyesters from renewable sources. However, achieving high selectivity for the C–O hydrogenation of the furan ring remains a significant challenge. In this study, we synthesized a series of trimetallic CuCoLa catalysts, using a coprecipitation method with various metal ratios. The reduced CuCoLa catalyst with a metal ratio of 1/3/1, exhibited the highest activity for the selective hydrogenolysis of FA to PeDs. Under optimal reaction conditions (160 °C, 4 MPa H2 for 9 h), CuCoLa(1/3/1)-R achieved yields of 21.7% for 1,2-PeD and 50.1% for 1,5-PeD. Furthermore, the catalyst remained stable after five cycles of FA conversion to PeDs. The high selectivity for PeDs is attributed to the synergistic interaction between Cu and Co and the appropriate number of basic surface sites.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
