“…A heterogeneous catalyst plays an important role in many established and emerging chemical processes, where high performance requires rational design using various synthesized strategies, tuning the geometric structure and microenvironment of active sites, such as coordination status and electronic properties 1–6 Therein, micro- and nanometer-sized materials with hollow interiors as catalysts have attracted particular attention, which demonstrate obvious advantages, such as effectively isolating catalytic species, improving mass transfer, and enhancing the selectivity by controlling pore sizes in the shells. This specific structure can help to achieve excellent performance in chemical synthesis, electrocatalysis, photocatalysis, energy storage and conversion, and other applications.…”

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.

Development of efficient and stable non‐noble metal catalysts applied to the catalytic transfer hydrogenation of nitroarenes under mild conditions is still challenging. Herein, we report magnetically recyclable catalysts prepared via simple two‐stage pyrolysis of Co‐MOF‐74 and melamine composites. The optimized catalyst Co@C/CNTs‐10‐700 shows excellent conversion and selectivity towards transfer hydrogenation of nitroarenes with different hydrogen donors. Its excellent stability against formic acid corrosion makes it can be used in a wide range. The excellent catalytic performance can be ascribed to the synergistic effect between carbon nanotubes and Co nanoparticles. Furthermore, the catalyst was easily recycled owing to its magnetism and reused up to ten consecutive cycles without significant loss of activity, indicating that the excellent catalytic stability holds great promise in fields of industrial application.
