摘要：

The wicker-like Pd-PVP-Fe (palladium-poly(N-vinylpyrrolidone)-iron) was synthesized by the external magnetic field (EMF). The Pd-based catalyst with nano and the face-centered cubic (fcc) structure was obtained at room temperature without using any additive. The resulting composite was characterized. The results show that EMF has a great influence on morphology, particle size, and crystalline structure of the Pd-PVP-Fe composite. The resulting composite (Pd-PVP-Fe), was found to be an effective catalyst for the Mizoroki-Heck reaction while is exposed to EMF with the intensity at 486 mu T. The reused catalyst for at least five repeating cycles, shows excellent activity. (C) 2016 Elsevier B.V. All rights reserved.
