Abstract:The application of biofuels could greatly alleviate energy crises and environmental problems caused by the overexploitation of fossil resources. Furfural is one of the most valuable bio-based platform compounds, and its derivatives, such as furfuryl alcohol, tetrahydrofurfuryl alcohol, 2-methylfuran, levulinates, furfuran ether, and γ-valerolactone, possess great potential as biofuels or fuel additives due to their high energy density and octane ratings. Furthermore, the study of furfural conversion to biofuels could significantly alleviate the energy crisis and aligns with the national "carbon peak" and "carbon neutrality" development strategies. This review overviews the production of biofuels from furfural through hydrogenation, hydrodeoxygenation, alcoholysis, and cascade reactions. The conversion process, reaction mechanisms, and catalytic progress are discussed, and the derived biofuels with different properties are briefly evaluated. Finally, the challenges in the conversion process are outlined to provide guidance for future research in this area. Close-
