“…The peak at 480 cm −1 in Figure 1a assigned to the Ce–O vibration of CeO 2 confirmed the presence of CeO 2 in catalysts AcCo‐2 and AcCo‐3. Raman spectra (Figure 1b) exhibited a strong peak around 460 cm −1 associated with the F 2g vibration mode of CeO 2 further confirmed the existence of CeO 2 in AcCo‐2 and AcCo‐3 29,30 . Raman experiment further was employed to examine the defects and structural changes for AcCo‐1 and AcCo‐3.…”

“…Raman spectra (Figure 1b) exhibited a strong peak around 460 cm À1 associated with the F 2g vibration mode of CeO 2 further confirmed the existence of CeO 2 in AcCo-2 and AcCo-3. 29,30 Raman experiment further was employed to examine the defects and structural changes for AcCo-1 and AcCo-3. Raman spectra showed two prominent peaks at 1360 and 1590 cm À1 , which can be ascribed to the surface defects (D) and the in-plan vibration of the sp2 carbon matrix (G), respectively, 31,32 as depicted in Figure 1b.…”

Since catalytic chemoselective reduction of corresponding nitroarenes is a significant route to produce functionalized anilines, developing inexpensive and highly active catalyst is imperia. Herein, the Co‐Ce‐H2salen‐hmta composite was first prepared by grinded completely the mixture of Co‐H2Salen and hexamethylenetetramine (hmta) in 1:1 mol ratio in a mortar. The 3d–4f hetero‐metal Co‐Ce‐H2salen coordination polymer acted as a support precursor and hmta provided the nitrogen source. Then, a target catalyst of Co/NC‐CeO2‐hmta were afforded by pyrolysis of Co‐Ce‐H2salen‐hmta composite at 800°C in the presence of argon atmosphere. When the target catalyst of Co/NC‐CeO2‐hmta and reference catalysts were applied for the hydrogenation of nitroarenes under N2H4, the target catalyst of Co/NC‐CeO2‐hmta exhibited better performance than reference catalysts in terms of conversion, yield, selectivity, and recyclability. Spectral analysis suggested that the high catalytic performance of a target catalyst of Co/NC‐CeO2‐hmta were attributed to highly dispersed metallic Co0, rich oxygen vacancies, and nitrogen‐doped carbon matrix.
