摘要：5-Hydroxymethylfurfural (HMF) hydrodeoxygenation to 2,5-dimethylfuran (DMF) plays a significant role in biomass conversion. Herein, we develop a facile CoMo bimetallic catalyst with CoN 4 single atom sites for this transformation, which exhibits superior performance than most previous works (TOF up to 28.7, more than 8 cycles). A synergistic catalytic effect between Co and Mo sites are disclosed, in which the Mo sites mainly take part in the adsorption of substrates, while the Co sites mainly realizes the activation of H 2 . The mechanistic studies demonstrate that 5-methyl-2-furaldehyde (MF) is the main reason for the production of 1,2-bis(5-methylfuran-2-yl)ethane (BMF), and the hydrogenation of the aldehyde group is the rate-determining step of this reaction. According to these insights into the mechanism, a two-step and one-pot process is exploited for the HMF hydrodeoxygenation, resulting in a higher DMF yield under milder conditions. ? 2022, The Authors.
