TiN and TiC as stable and promising supports for oxygen reduction reaction: Theoretical and experimental study
Instability of catalyst supports is a primary reason for energy loss in proton exchange membrane fuel cells. In this study, Pt/TiN and Pt/TiC catalysts were synthesized by a solvothermal process. Density functional theory calculations revealed smaller distortion energies of Pt13 cluster and larger i...

In this study, Pt/TiN and Pt/TiC catalysts were synthesized by a solvothermal process. Density functional theory calculations revealed smaller distortion energies of Pt13 cluster and larger interaction between the Pt-TiN and Pt-TiC systems. The partial density of state calculations demonstrated that the Pt-d and C-p states and Ti-d and N-p states are energetically favorable and allow Pt-C-Ti and Pt-N-Ti to strongly bind to the TiC or TiN supports. As a result, Pt/TiN and Pt/TiC showed excellent durability as electrocatalysts. | ||

TiN and TiC as stable and promising supports for oxygen reduction reaction: Theoretical and experimental study |
| abstract |
Instability of catalyst supports is a primary reason for energy loss in proton exchange membrane fuel cells. In this study, Pt/TiN and Pt/TiC catalysts were synthesized by a solvothermal process. Density functional theory calculations revealed smaller distortion energies of Pt13 cluster and larger interaction between the Pt-TiN and Pt-TiC systems. The partial density of state calculations demonstrated that the Pt-d and C-p states and Ti-d and N-p states are energetically favorable and allow Pt-C-Ti and Pt-N-Ti to strongly bind to the TiC or TiN supports. As a result, Pt/TiN and Pt/TiC showed excellent durability as electrocatalysts. |
