Abstract

Supported nanocatalysts with environmental sustainability and high catalytic performance have attracted much attention. A supported nanocatalyst Co@NSC has been studied in this paper. Porous materials with catalytic properties were prepared by anchoring transition metal cobalt onto porous materials doped with nitrogen. The results of the scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) tests demonstrate that the catalyst obtained exhibits an excellent mesoporous structure and a uniform distribution of cobalt elements. The scaffold is rich in N atoms, which can provide enough anchor sites for cobalt to form cobalt-NX. Cobalt groups can improve the catalytic activity of the catalyst. In addition, Co@NSC is porous, the structure has the potential to facilitate the mass transfer of the reactants. In addition, the porous structure of Co@NSC is beneficial to facilitate the mass transfer of reactant. The prepared catalyst performs well in hydrogenating quinolone to corresponding N-formyltetrahydroquinoline. Subsequently, the selectivity and stability of the prepared catalyst were validated.

制备用于催化喹啉还原为 N-甲酰四氢喹啉的介孔壳聚糖钴载体纳米催化剂

具有环境可持续性和高催化性能的负载型纳米催化剂备受关注。本文研究了负载型纳米催化剂Co@NSC。将过渡金属钴锚定在掺杂氮的多孔材料上，制备了具有催化性能的多孔材料。扫描电镜（SEM）、x射线衍射（XRD）和傅里叶变换红外光谱（FT-IR）测试结果表明，所制备的催化剂具有优良的介孔结构，钴元素分布均匀。支架含有丰富的N原子，可以为钴提供足够的锚定位点，形成钴- nx。钴基团可以提高催化剂的催化活性。此外，Co@NSC是多孔的，其结构有可能促进反应物的传质。此外，Co@NSC的多孔结构有利于反应物的传质。所制备的催化剂在将喹诺酮加氢生成相应的n -甲酰基四氢喹啉方面表现良好。随后，对制备的催化剂的选择性和稳定性进行了验证。图形抽象

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
