Caption

PVDC undergoes dehalogenation in the presence of KOH, removing Cl and H functional groups to generate the clean byproducts KCl and H2O. The dehalogenated carbon sites exhibit very high reactivity, coupling with H3BO3 to form C–B or C–O–B bonding. Thereafter, the B-doped C is obtained by inert annealing B-doped polymeric C. The SEM and HRTEM images of O-BC-2-650, which evidence a 3D interconnected porous structure and an amorphous state with short-range graphitization. Moreover, the uniform distribution of B and O in the carbon matrix.
