Weshowed that electric arc discharge between graphite electrodes may be optimized to produce graphitized structures with avariety of graphene fragment sizes, forms, and interconnections between them. It also allows to introduce boron heteroatominto graphite-like structure. The as-synthetized material shows the hydrogen binding energy twice as high as unsubstitutedcarbons, but requires post-treatment (activation) as the its surface is low (~200 m2/g). %G English %L hal-02116568 %U https://hal.science/hal-02116568 %~ CNRS %~ UNIV-AMU %~ L2C %~ INC-CNRS %~ MADIREL %~ MIPS %~ UNIV-MONTPELLIER %~ TEST-HALCNRS %~ UM-2015-2021 %~ TEST2-HALCNRS
