The origin of the metal enrichment of carbon nanostructures produced by laser ablation of a carbon–nickel target

Solid state synthesis of Ru–MC with highly dispersed semi-embedded ruthenium nanoparticles in a porous carbon framework for benzoic acid hydrogenation

“…So far, a number of synthetic protocols, including thermal pyrolysis of organic compounds, [15][16][17] arc-discharge methods, [18][19][20] laser ablation, 21,22 and chemical vapor deposition [23][24][25] have been developed for the preparation of doped carbon nanomaterials with different sizes, shapes, and chemical compositions. Despite their general feasibility, all of these methods typically suffer from several limitations.…”
