摘要: Herein we report the fabrication of monodispersed poly(N-vinyl-2-pyrrolidone) supported palladium–cobalt nanomaterials (3.45 ± 0.36 nm) and their outstanding efficiency as catalysts in dimethylamine-borane dehydrogenation. By use an ultrasonic double reduction method, palladium cobalt cations were co-reduced PVP solution then prepared nanocatalysts characterized by UV-Vis, XRD, XPS HR-TEM-EDX analyses. The could be easily reused, at extremely low concentrations temperature they showed record catalytic activity, giving best performance yet with a very high turnover frequency (330.94 h−1) Ea value 50.78 2 kJ mol−1 for DMAB dehydrocoupling.
