| 제목 | Pd nano-octahedron catalyst with Pt doped by Galvanic replacement for direct synthesis of hydrogen peroxide |
| 초록 | A previous DFT calculations showed that Pd {111} is more effective in direct synthesis of H2O2 than Pd {100}[1] and this was realized by an experimental result that Pd octahedrons showed much higher H2O2 selectivity/productivity than Pd cubes did[2]. In addition, when a small amount of Pt was added to Pd, H2O2 selectivity and productivity considerably increased[3]. In this research, (1) we simulate direct synthesis of H2O2 on Pd {111} which is doped with Pt atoms using DFT calculations, then (2) realize it by synthesizing Pt-doped Pd octahedron and performing activity tests to observe how selectivity and productivity change as Pt/Pd ratio increases. To replace Pd atoms on the surface with Pt atoms, we performed Galvanic replacement. Pt-doped Pd octahedrons showed H2O2 productivity almost twice as high as Pd octahedrons did. 1. P.
