Selective tailoring of covalent bonds on graphitized hollow carbon spheres towards controllable porous structure and wideband electromagnetic absorption

Recently, the exploration of a new strategy to create pores on carbon frameworks has received great interest. Herein, the selectively tailoring of the covalent bonding method has been shown to be one of the effective methods to generate pores based on graphitic hollow carbon frameworks (HGC). The mechanism of porous structure formation is due to directional clipping of sp2 C–C- and CO covalent bonds into C–O bonds. Due to the effectively ability...
