Abstract

Core-shell Fe3O4@C nanoparticles consist of a magnetic core and carbon coating, and exhibit high adsorptive capacity, easy magnetic separation and reusability. Due to these properties, core–shell Fe3O4@C nanoparticles have great potential application in adsorption, separation and wastewater treatment. Magnetic separation based on the super paramagnetic Fe3O4 has received considerable attention and is widely used for the removal of dye, oil pharmaceuticals and metals from water due to its high efficiency and economic viability. Therefore, the main characteristics of the core-shell Fe3O4@C nanoparticles, the different types of synthesis, as well as the main applications for the removal of water pollutants were reviewed. In this brief review, an overview of the basic properties of the Fe3O4@C core-shell nanoparticles are given, and the most important and more frequently used methods for the synthesis of Fe3O4@C core-shell nanoparticles have been summarized along with the description of its adsorbent application potential.
