2,5-Bis-(hydroxymethyl)furan (BHMF) is an important biomass-based platform chemical that can be derived from the hydrogenation of biomass-based 5-hydroxymethylfurfural (HMF). In this paper, the formation of BHMF from HMF via the catalytic transfer hydrogenation (CTH) process, using isopropanol as the hydrogen source and Ru/Co 3 O 4 as the catalyst, was studied. The results revealed that the Ru/Co 3 O 4 catalyst displayed a high catalytic efficiency, and that a BHMF yield of up to 82% was obtained at 190 • C in 6 h. Moreover, it was found that the recovered Ru/Co 3 O 4 exhibited a similar catalytic activity to the pristine Ru/Co 3 O 4 catalyst. These results supported the conclusion that the present CTH process is an attractive green route for the synthesis of BHMF from biomass-based HMF.
