Selenium and nitrogen co‐doped porous carbon immobilized Ag nanoparticles: A practical heterogeneous nanocatalyst for hydrogenation of nitroaromatics

Abstract

Silver nanoparticles (Ag NPs) supported on selenium and nitrogen co‐doped mesoporous carbon were prepared through pyrolysis of glucose, ammonium chloride (NH4Cl), and selenium dioxide (SeO2) as the carbon, nitrogen, and selenium sources, followed by a chemical reduction strategy. The synthesized Ag/m‐SeNC could catalyze the hydrogenation of a series of nitroaromatics to corresponding amines effectively in an aqueous solution in the presence of NaBH4 as a hydrogen donor. Besides, this heterogeneous nanocatalyst could be simply reused four successive times without significant reduction in activity and selectivity.

Selenium-doped carbon materials: synthesis and applications for sustainable technologies

“…Nemati et al utilized Se/N dual-doped carbons as support for Ag and Pd NPs. 87,88 Besides surface functionalization, there is an extensive number of examples of selenium/carbon composites where Se occurs in its elemental form. Porous carbons can bear large amounts of Se, while Se has the advantages of electric (semi)conductivity and high stability in acidic solutions.…”

“…For instance, Ag NPs supported on Se/N co-doped mesoporous carbon catalyzed the hydrogenation of a series of nitroaromatics to corresponding amines. 87 Similarly, the Pd NPs supported on the Se/N dually doped carbon support catalyzed the Heck cross-coupling reaction (C-C bond formation via Heck-Mizoroki cross-coupling reaction). 88…”

“…Further, among the various heteroatom dopant that is candidate to introduce to thein to the carbon latex, Se is one of the less known cases. [7][8][9] To date, the palladium (Pd)-catalyzed cross-coupling reaction (e.g., Sonogashira-Haghihara, Mizoroki-Heck, and Suzuki-Miayura) is one of the most mighty and indubitable manner to structure the new C-C bonds in both industry and chemical transformation due to their high selectivity, different functional groups endurances, and especially their acceptable regio-stereo selectivity. Among the divers of C-C bonds formation, the olefination between haloarenes (ArX, X: F, Br, Cl, and I) and vinyl groups, also known as the Mizoroki-Heck cross coupling reaction, is one of the substantial strategies to production the new types of applicable products that are notably founded in natural products, polymers, dyes, herbicides, and pharmaceutical industries.…”
