Preparation of mesoporous chitosan cobalt supported nano-catalyst for the catalyzed reduction of quinoline to quinoline aldehyde

Supported nanocatalysts with environmental sustainability and high catalytic performance have attracted much attention. Research interest in sustainable catalysis. 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. Carbon material with chitosan as raw material. 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 points 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, thereby enhancing the overall efficiency of the reaction. Furthermore, the prepared catalyst was employed in the conversion of quinoline into the corresponding quinoline aldehyde. The results show that quinoline can be directly reduced to produce the corresponding quinoline aldehyde. Subsequently, the selectivity and stability of the prepared catalyst were validated.
