Catalytic Reduction of 4-Nitrophenol with Polydopamine-grafted Boron Nitride Nanosheet Decorated with Gold Nanoparticles |
| 초록 |
Gold nanoparticle (AuNP)-decorated boron nitride nanosheet (BNNS) was successfully prepared through the simultaneous reduction of Au3+ ions and the growth of AuNPs on polydopamine (PDA)-grafted BNNS. BNNS-AuNP showed remarkable dispersion stability in aqueous media and revealed high catalytic efficiency for the reduction of nitrophenol as (4-NP) into 4-aminophenol (4-AP) within 8 min in water. 2D structural feature of BNNS-AuNP also enables isolation and recycling of catalyst from 4-AP through the ultracentrifugation, which shows the retention of more than 60% of catalytic activity of BNNS-AuNP after 5 times of recycling steps. |
