The models for PtNC are supported on the (a) surface oxygen of Mo2TiC2, (b) Mo of Mo2TiC2, and (c) Pt (111) surface. ΔEMSI: strength of the metal-support interaction. d The d-electron structure of on-surface Pt atoms on the Pt (111) surface and Mo2TiC2-PtNC, including LC-Pt and MoC-Pt, respectively. e Free energy diagram of hydrogen evolution at zero potential and pH 0 for the Pt (111) surface and Mo2TiC2-PtNC, including LC-Pt and MoC-Pt. Atomic coordinate dataset is provided as Supplementary Data 1, other source data are provided as a Source Data file.
