Fe3O4@SiO2@l‐arginine@Pd(0): a new magnetically retrievable heterogeneous nanocatalyst with high efficiency for C–C bond formation. (9th February 2016) - Ghorbani‐Choghamarani, Arash
Abstract : The surface of Fe3 O4 @SiO2 nanoparticles was modified usingl ‐arginine as a green and available amino acid to trap palladium nanoparticles through a strong interaction between the metal nanoparticles and functional groups of the amino acid. The proposed green synthetic method takes advantage of nontoxic reagents through a simple procedure. Characterization of Fe3 O4 @SiO2 @l ‐arginine@Pd(0) was done using Fourier transforminfrared spectroscopy, thermogravimetric analysis, scanningelectron microscopy, energy‐dispersive X‐ray spectroscopy, X‐ray diffraction, vibrating sample magnetometry andinductively coupled plasma analysis. Thecatalytic activity of Fe3 O4 @SiO2 @l ‐arginine@Pd(0) as a new nanocatalyst was investigated inC– C coupling reactions . Waste‐free, use of green medium, efficient synthesis leading to high yield of products, eco‐friendly and economic catalyst, excellent reusability of the nanocatalyst and short reaction time are the main advantages of the method presented.
