Abstract

Catalysts play a critical role in the selective conversion of furfural (FAL) in the aqueous-phase hydrogenation-rearrangement tandem reaction (AP-HRT). Herein, the N-doped bimetallic Ni-Co@NOMC was synthesized by solvent volatilization self-assembly method. The morphology and structure of the APF precursors were effectively controlled through adjustments in the synthesis and the presence of numerous pore channels and the substantial specific surface areas contributed to enhancing catalytic efficiency. Furthermore, this study also examined the synergistic interaction between the acid-base sites of the novel mesoporous N-doped carbon (NOMC) carrier and metal active sites to advance the succession of the furan ring hydrogenation and rearrangement processes. Specifically, the 99.9 % conversion of 8 wt% FAL solution was successfully accomplished with the 90.5 % selectivity of cyclopentanone catalyzed by 1.2-Ni-Co@NOMC catalysts. Therefore, this research holds significant importance for advancing the sustainable utilization of biomass resources in the future.

Ni-Co@NOMC 的合成及其活性位点在糠醛选择性转化为环戊酮过程中的调节作用

在水相加氢-重排串联反应（AP-HRT）中，催化剂在糠醛（FAL）的选择性转化中起着至关重要的作用。本文采用溶剂挥发自组装法合成了掺杂N的双金属Ni-Co@NOMC。在合成过程中，通过调整有效地控制了 APF 前驱体的形貌和结构，大量孔道和比表面积的存在有助于提高催化效率。此外，本研究还考察了新型介孔掺杂 N-碳（NOMC）载体的酸碱位点与金属活性位点之间的协同作用，以推进呋喃环氢化和重排过程的连续进行。具体而言，在 1.2-Ni-Co@NOMC 催化剂的催化下，8 wt% FAL 溶液的转化率达到 99.9%，环戊酮的选择性达到 90.5%。因此，该研究对推动未来生物质资源的可持续利用具有重要意义。
