Preparation of palladium nano-raspberry using peptide as a template and its catalytic property in C-C coupling reaction |
| 초록 |
Nano materials have received a lot of attention from various research areas because of their unique physical and chemical properties. They show drastic changes in catalytic, magnetic, and optic properties, depending on their size and morphology. To control these properties, various methods have been tried so far. In biological systems, they are produced by so-called bio-mineralization process. To mimic this process, series of tyrosine containing peptides were synthesized to control the shape of metal nano particles (NPs). We found that the palladium ions could be reduced to Pd NPs (5-6 nm) by our specific tyrosine peptide. The folding and conformational change of the peptide by Pd ions induced the NPs to form a raspberry-like structure. Additionally, these raspberry shaped Pd NPs showed good catalytic activities in copper-free Sonogashira cross-coupling reaction in water. |
