Oxygenated group and structural defect enriched carbon nanotubes for immobilizing gold nanoparticles†
Abstract
Surface functionalized and defect enriched carbon nanotubes (oCNTs) by green ozone/H2O treatment can efficiently anchor gold nanoparticles. This Au/oCNT could be stabilized and well dispersed after thermal treatment and showed robust catalytic activity (20.6 mmol gcat−1 h−1) for the oxidative self-coupling of benzylamine to imine in solvent free conditions.
