Fig. 2: Structure characterization of H-CuCo.
From: Unconventional hexagonal open Prussian blue analog structures

a–c SEM image (a) and TEM images (b, c) of H-CuCo. d SAED pattern of H-CuCo along the [\(1\bar{1}0\)] zone axis. e Cs-HRTEM image taken from the white square-marked area in (c) and the corresponding FFT pattern as inset. f Crystal model of the lattice structure of H-CuCo along the [\(1\bar{1}0\)] zone axis. The orange, gray, and blue balls represent the Cu, C, and N atoms, respectively. g–k HAADF-STEM image (g) and the corresponding elemental mappings (h–k) of H-CuCo.
