Facile synthesis of uniform magnetic graphitic carbon for an efficient adsorption of pentachlorophenol

Abstract

Uniform core–shell structured magnetic graphitic carbon (Fe₃O₄@SiO₂@g-C) nanospheres were fabricated via a two-step Stöber coating strategy, followed by a carbonization process in N₂ atmosphere. The resultant composites possess a large magnetic susceptibility (25 emu g⁻¹) and a high graphitization degree, making it an excellent magnetically separable adsorbent for the removal of pentachlorophenol.
