Microscopy characterizations of 1% Pt/MXene catalysts. a Representative HAADF-STEM image of 1% Pt/Ti3C2Tx catalyst. b (111) surface of Pt3Ti NP. Inset is a simulated STEM image of Pt3Ti (111) surface. The simulated image is in good agreement with the experimental result. c Schematic illustration of RMSI in Pt/MXene catalysts and the structure of L12-ordered intermetallic Pt3Ti. d Representative HAADF-STEM image of 1% Pt/Nb2CTx catalyst. e A Pt-Nb NP viewed along [111], inset is the FFT pattern of the NP. f IFFT pattern of the NP in Fig. 2e, inset is an enlarged image showing the super lattice of the NP. Scale bars: a, d, e 2 nm, and b 500 pm
