▎ 摘　　要

To optimize the technological development together with energy gain, the crucial materials needs to be tailored in a smart way to benefit a maximum from the property-structure relation. Herein we propose the way to increase a defect density in graphene moving from 1D linear edges to fractal edges, also highlight the fractal nature of graphene structures them-self. The tentative oxidation and hydrogenation catalytic etching of few layer graphene results in structures with edges fractals, jaggy edges at graphene periphery or in newly formed etched holes.
