Nitrogen-doped coatings on carbon nanotubes and their stabilizing effect on supported Pt nanoparticles

For the preparation of the coating the CNTs were dispersed in a 30 wt% solution of 3MBP-dca in deionised water by sonication. The resulting black slurry was filtered by vacuum filtration and the black residue in the filter was washed with 50 mL of ethanol to remove excess IL. The residue was subsequently placed in ceramic crucible and thermally treated in a furnace under constant argon flow to 1000 °C applying a heating rate of 100 K h -1 . After 1 h at 1000 °C the sample was allowed to cool down to room temperature and subsequently pestled for further use.
