The synthesis of bis(5-methylfuran)methane (BMFM) from biomass-based 5-methylfurfural (5-MF), a vital fuel precursor, is crucial for biomass refining. However, selective BMFM production 5-MF needs to suppress side reactions such as hydrogenolysis and decarbonylation. Therefore, direct hydrogenation into very challenging in sustainable valorization. In this study, we developed bimetallic RuCu/hydroxyapatite (HAP) catalyst 5-MF. RuCu/HAP delivered yield 75.6% under mild reaction conditions (V water : V cyclohexane = 1 1, 4 MPa H2, 100 °C, h), significantly surpassing its monometallic counterparts (Ru/HAP: 28.7%; Cu/HAP: 0%). Furthermore, 79% C11 straight-chain alkanes was obtained through the hydrodeoxygenation (HDO) process. systematic characterization revealed that Ru mediates steps via C[double bond, length m-dash]O activation, while Cu orchestrates acid sites essential self-condensation 5-MFA. synergistic interplay between metallic acidic thereby enables simultaneous optimization conversion efficiency selectivity. These findings provide practical efficient route converting lignocellulosic derivatives renewable biofuels, particularly aviation applications.
