چکیده انگلیسی
Addressed herein, the synthesis of the monodisperse poly(3,4-ethylenedioxythiophene)(PEDOT) supported palladium-nickel nanomaterials (3.32 ± 0.36 nm) and their applications as a catalyst in dimethylamine-borane (DMAB) dehydrogenation is outlined. Microwave assistance procedure was used in preparation of nanomaterials where palladium and cobalt cations were reduced in PEDOT solution (Pd-Ni@PEDOT) in microwave conditions. The characterization of the nanocatalyst was performed by using UV-VIS, XRD, XPS, TEM and HR-TEM-EELS analyses. The Pd-Ni@PEDOT NPs were found to be highly effective and stable for the dehydrogenation of DMAB. The catalytic activity of Pd-Ni@PEDOT was one of the highest one among the all prepared catalysts in literature even at lower temperatures and concentrations, yielding to give high turnover frequency (451.2 hâ1) and low Ea (50.78 ± 2 kJ/mol) for dehydrocoupling of DMAB.
