| 英文摘要 | Selective hydrodeoxygenation (HDO)/hydrogenolysis of phenolics to produce arene in liquid-phase conditions is a key challenge in biomass valorization. Cost-effective base-metal catalysts are intriguing for this application, yet they typically suffer from inferior performance compared to precious metals. Herein, we report a Cs-G@CoFe catalyst with a bimetallic alloy core and graphene overlayers doped with Cs, on which HDO of phenol with >90% benzene selectivity was achieved under liquid-phase conditions. More importantly, the bimetallic catalyst showed a significantly enhanced activity (>threefold) compared with the monometallic Fe-based catalyst. A combination of characterizations confirmed the formation of a CoFe alloy core wrapped by several graphene overlayers in the Cs-G@CoFe catalyst. In contrast to the inhibited C-O cleavage product by the addition of Cs in the Cs-G@Fe catalyst, the addition of Cs on Cs-G@ CoFe improved the activity for selective C- O bond cleavage. The surface chemistry has been probed using H2 chemisorption to identify the enhanced activity in the selective hydrogenolysis of phenolics. |
