제목 Virus-guided Self-mineralization of Ligand-free Palladium Nanowires for High and Stable Catalytic Activity
초록 We investigate the impact of ligand-free surface activity and structural stability of virus-templated palladium nanowires (PdNWs) on their performance for catalytic application. A genetically modified M13 virus is employed as a negatively charged template to induce the electrostatic complexation with positive Pd precursors for the spontaneous mineralization of PdNWs. The well-entangeld network structure of PdNWs prevents the aggregation of Pd, maintaing large active surface area. In addtion, stabilizer-free clean surface of PdNWs enables high catalytic acitivity for the Suzuki-coupling reaction. This research was supported by Nano·Material Technology Development Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT and Future Planning (NRF-2017M3A7B4052798).
