a Schematic of the synthesis process of Mo2TiC2-PtNC. b SEM and TEM images of few-layer Mo2TiC2. c TEM image of Mo2TiC2-PtNC. d Size distribution of the Pt nanoclusters. e HADDF-STEM image of the nanoclusters. f XRD spectra of Mo2TiAlC2, Mo2TiC2, and Mo2TiC2-PtNC. g Normalized XANES spectra at the Pt L3-edge of PtO2, Mo2TiC2-PtSA, Mo2TiC2-PtNC, rGO-PtNC and Pt foil. h k3-weighted Fourier transform of EXAFS spectra derived from the EXAFS spectra of PtO2, Mo2TiC2-PtSA, Mo2TiC2-PtNC, rGO-PtNC, and Pt foil. R is the interatomic distance. i High-resolution XPS spectra (Pt 4f) of Mo2TiC2-PtSA, Mo2TiC2-PtNC, rGO-PtNC and Pt foil. (The circles represent raw data, and the lines represent fitting data and base line.) j DEMS measurements of Mo2TiC2-PtSA, Mo2TiC2-PtNC, rGO-PtNC and Pt/C-20%, the onset potentials were determined at points where the signal-to-noise ratio exceeded 5.
