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

Silver nanoparticles (Ag NPs) supported on selenium and nitrogen co‐doped mesoporous carbon were prepared through pyrolysis of glucose, ammonium chloride (NH 4 Cl), and selenium dioxide (SeO 2 ) 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 NaBH 4 as a hydrogen donor. Besides, this heterogeneous nanocatalyst could be simply reused four successive times without significant reduction in activity and selectivity.
