Abstract
Tetrahydrofurfuryl alcohol (THFAL), as a green industrial solvent, can be obtained directly from biomass-derived furfural with 100% conversion and 100% yield over a hydroxyapatite-supported Pd catalyst (Pd-HAP) under relatively mild conditions (40 °C, 1 MPa H2, and 3 h) in 2-propanol. At room temperature and reacting for 8 h, the yield of THFAL was more than 99%. By capturing the intermediates, two pathways were proposed as follows: (1) Furfural was partially hydrogenated to furfuryl alcohol, and then, furfuryl alcohol was further hydrogenated to THFAL. (2) Furfural and 2-propanol first formed 2-(isopropoxymethyl)furan (2-IPMF) via etherification, and then, 2-IPMF was ultimately converted to THFAL. The Pd-HAP catalyst was characterized by various techniques including XRD, SEM, TEM, HAADF-STEM, XPS, and ICP-AAS. The results revealed that the outstanding catalytic performance of Pd-HAP was attributed to the quasicoordination effect between Pd and HAP, which not only contributed to highly dispersed and stabl...
