Article history: A series of meso- and microporous carbons containing magnetic Ni nanoparticles (Ni/C) with a Received 11 June 2015 variety of Ni loadings were synthesized by a simple one-pot procedure through carbonization of Received in revised form 2 October 2015 resorcinol–formaldehyde polymers containing various amounts of nickel(II) acetate. Such composite Accepted 6 November 2015 materials were characterized by N sorption, Raman spectroscopy, X-ray diffraction (XRD), scanning Available online 10 November 2015 electron microscopy (SEM) and Transmission electron microscope (TEM). The XRD patterns reveal peaks corresponding to face centered cubic nickel with the average size of crystallites of 17–18 nm. SEM and TEM Keywords: results reveal that the formation of the nanoparticles took place mainly in the carbon spheres (1–2 m Resorcinol–formaldehyde polymers in size) and on the outer surface as well. The as-prepared composites are characterized by a core–shell Carbon–nickel composites structure with well-crystallized graphitic shells about 8–15 nm in thickness. The Raman spectra show Magneto-sensitive sorbents that Ni content inﬂuences the structure of the carbon. It was also shown that the morphology (particle Core–shell structure Char shape and sizes) and porosity (pore volume and pore size distribution) of the chars are strongly depen- Particle morphology dent on
