Morphologies and structures of 2DA and 2DPA. a, b TEM images (insets: SAED patterns) of 2DA (a) and 2DPA (b). c, d HRTEM images (insets: FFT patterns) of 2DA (c) and 2DPA (d). Scale bars, 20, 2, 20 and 2 nm in a, b, c and d, respectively. e–i Raman, FTIR, 1H NMR, Ni 2p3/2 XPS spectra and O 1 s XPS spectra of 2DA (orange) and 2DPA (purple). j Schematic representation of the preparation processes of the four samples. Ni: blue balls, O: pink balls, H: cyan balls
