“…However, the production of hydrogen from 2-propanol usually requires higher temperatures and longer reaction times as observed, 50 On the contrary, addition of hydrogen from sources other than molecular hydrogen and alcohols (e.g. ammonia borane, 51 formic acid, 52 hydrazine hydrate 53,54 etc.) has emerged as much safer alternatives in recent times.…”

Integrating MOFs as precursor, especially for employing N-containing organic linkers, with sulfides is an effective method to prepare the highly efficient N-doped carbon supported metal-based catalysts for hydrogenation of nitroarenes. In this work, a N,Fe-containing metal organic frameworks (MOFs; termed as MIL88-HMTA) with spindle-like structure was prepared via self-assembly method, in which hexamethylenetetramine (HMTA) linker was introduced as N source. Subsequently, N-doped carbon supported FeS x -Fe 2 O 3 catalyst (named FeS x -Fe 2 O 3 @CN) was fabricated upon the pyrolysis of sulfurized MIL88-HMTA. Catalytic experiments reveal that the FeS x -Fe 2 O 3 @CN delivered excellent performance for hydrogenation of nitroarenes in comparison with those of catalyst without sulfidation process (Fe 2 O 3 @CN) and conventional MIL88 derived catalyst (Fe 2 O 3 @C). The XRD, TEM, SEM/EDX, Raman, UV, and XPS analyses have revealed that the developed FeS x -Fe 2 O 3 @CN catalyst exhibited outstanding catalytic efficiency was ascribed to synergistic effect between FeS x and Fe 2 O 3 species, abundant structural defects, more Fe-N x species, and strengthened decomposition ability of hydrazine hydrate (N 2 H 4 ÁH 2 O). Furthermore, the effect of sulfidation ratio (the mass ratio between thioacetamide and MIL88-HMTA) towards preparation of the developed FeS x -Fe 2 O 3 @CN on the catalytic activity of hydrogenation reaction was also systematically performed. Notably, the optimized catalyst (denoted as FeS x -Fe 2 O 3 @CN-8) exhibited unexpected performance and recyclability for hydrogenation of nitroarenes under mild condition. The pyrolysis of sulfurized N-containing MOFs may present a facile approach for fabricating MOFsderived N-doped carbon supported catalysts, which provides a potential application in heterogeneous catalytic reactions.

“…Although, considerable progress has been demonstrated for the preparation of the effective catalyst, but finding the new ones, which has good catalytic performance, great intrinsic activity as well as achieving high standard industrial protocol in mild reaction condition is still of great interest. Among them, heterogeneous catalysts containing noble metal catalysts (Pd, Pt, Rh, Ru, Au, and Ag) have received great attention in diverse researches because of excellent catalytic activity in different organic transformations as well as the reduction of nitro compounds …”

In this study, a new precursor was synthesized form the reaction of melamine and chloroacetonitrile. By using this pre‐material, the new mesoporous triazine based‐carbon material was prepared during ionothermal process with the help of ZnCl2, and used as the excellent support for silver nano‐particles. The new nano‐catalyst was named Ag/mCTF(mesoporous Carbon Triazine Framework), and fully characterized by various analytical methods including Fourier transformed infrared spectroscopy (FT‐IR), field emission scanning electron microscopy (FE‐SEM), energy‐dispersive X‐ray spectroscopy (EDX), X‐ray diffraction (XRD) and thermogravimetric analysis (TGA). The catalyst ability of Ag/mCTF was survived in the reduction reaction of nitroaromatic compounds. The results show that this new catalyst produced anilines in good yields in benign condition. The other merit of this heterogeneous catalyst was high recyclability without significant decrease in its performance.
