Preparation and characterization of polymer-supported nano-amorphous Ni–B particles
Source abstract
Abstract
Polymer-supported nano-amorphous Ni–B particles have been prepared by an ion exchange/chemical reduction protocol. The products were characterized by inductively coupled plasma spectroscopy (ICP), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The polymer-supported Ni–B particles prepared at low temperature are 60–70 nm in size with a Ni–B ratio of Ni19B10.The choice of temperature is a crucial factor affecting particle size.
