| 제목 | DFT calculation and nanoparticle synthesis on Pd nano-octahedron surface doped with Pt by Galvanic replacement reaction as a catalyst for direct synthesis of H2O2 |
| 초록 | Direct synthesis of H2O2 has been suggested as an alternative to replace the conventional AO process. However, it includes three spontaneous side reactions, which causes low selectivity. DFT calculation can demonstrate structural effects of nanoparticle by simulating a reaction on specific structure of atoms, and the results are realized by nanoparticle synthesis. In this research, we simulate direct synthesis of H2O2 on Pt-doped Pd(111) by DFT, then realize it by synthesizing Pt-doped Pd octahedra and perform activity tests to observe how selectivity and production rate change as Pt/Pd ratio increases to find the optimal Pt/Pd ratio. To replace Pd atoms on the surface with Pt atoms, Galvanic replacement reaction was performed. As a result, Pt-doped Pd octahedra catalyst showed production rate almost twice as high as pure Pd octahedra did. |
