| 英文摘要 |
We herein report, for the first time, a bifunctional base-metal catalyst
(Co@HZSM-5) that acts as an efficient alternative to noble-metal catalysts (e.g.,
Pt, Ru) for the conversion of levulinic acid into valeric biofuel under batch and
fixed-bed reactor conditions. The cobalt nanoparticles were embedded in HZSM-5
crystals and catalyzed the sequential hydrogenations of the ketone and alkene
functional groups; meanwhile, the acidic zeolite catalyzed the ring opening of the
?-valerolactone intermediate. Although base metals (e.g., Co) are abundant and
inexpensive, their sintering and/or leaching under liquid-phase conditions always
lead to the irreversible deactivation of the catalyst. In this system, the embedment
structure stabilizes the nanoparticles, and Co@HZSM-5 could be used up to eight
times. This work provides a practical clue toward the stabilization of base-metal
catalysts and will inspire the development of large-scale biorefinery. |
