Cobalt ferrite (CoFe 2 O 4 ), with good chemical stability and magnetic loss, can be used to prepare composites with a unique structure and high absorption. In this study, CoFe 2 O 4 @mesoporous carbon hollow spheres (MCHS) with a core-shell structure were prepared by introducing CoFe 2 O 4 magnetic...
