چکیده مقاله

Porous carbon-based materials have become one of the hot topics in a wide range of fields due to their low-cost preparation, excellent electrical and thermal conductivity, and high surface area [1]. Recenly, heteroatoms doping has been widely developed as an effective strategy to modulate the electronic structure of carbon frameworks, improve their physicochemical properties, and strengthen interactions with metal species, thereby enhancing catalytic performance [2]. Metal-organic frameworks (MOFs) have emerged as ideal precursors for synthesizing heteroatom-doped-carbon materials [3]. In this work, N and S co-doped porous carbon-supported Cu2S NPs (Cu2S@CNS) were synthesized using simple one-pot pyrolysis of mixture of MOFs (HKUST-1) and thiourea under an inert atmosphere at 400 ℃. The structural and morphological features of the prepared material were investigated using XRD, BET, EDX, TGA, MAP, FT-IR, TEM, and FE-SEM analyses. The catalytic activity of the Cu2S@CNS-400 was evaluated in A3 coupling reaction of benzaldehyde, morpholine, and phenylacetylene, affording the corresponding propargylamine in high yield and short reaction time. The use of inexpensive precursors, facile synthetic route, mild and solvent-free reaction conditions, and excellent catalytic efficiency are some of the benefits of this protocol.
