Abstract

A simple and effective method has been developed to assemble the β-Co(OH)2 nanoparticles coordinated to the surface of the reduced graphene oxide sheets. The reduced graphene oxide-Co(OH)2 hybrid is characterized by transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy techniques, respectively. These morphological and structural analysis results demonstrate the successful attachment of hexagonal β-Co(OH)2 nanoparticles to the reduced graphene oxide sheets through the oxygen-containing functional groups. Compared to the paramagnetic property of hexagonal β-Co(OH)2 nanoparticles, a s-like superparamagnetic behavior can be observed at room temperature for the reduced graphene oxide-Co(OH)2 hybrid by the magnetometer PPMS-9T magnetic measurement, indicative of superparamagnetism. The interplay between the localized magnetic moment of the Co2+ ions in the hexagonal β-Co(OH)2 nanoparticles and the itinerant π carriers in reduced graphene oxide is suggested to be responsible for this superparamagnetic behavior. This enhanced magnetism indicates that the reduced graphene oxide-Co(OH)2 hybrid has a promising potential for spintronic device applications.
