1. XRD patterns of MAX (black), MXene (red) and Ge/MXene (blue)
2. SEM images of Ge/MXene
3. Morphology with analysis of Ge/MXene (a-c) TEM image of Ge/MXene; (b) Low magnification TEM image, the arrows points to typical MXene layers; (c) High magnification TEM image and thin carbon layer around Ge nanoparticle; (d) HADDF image of Ge/MXene; EDS mappings of (e) C, (f) Ti and (g) Ge
4. XRD patterns (a) of Ge/MXene with different annealing time and their TEM images (b-c) 0.5 h; (d-e) 1.5 h; (f) 3 h. Peaks marked with solid circles are from MXene and with cross are from Ge
