Crystalline facets and degradation pathway. a Top, HR-TEM image of one 41 nm CuNC along the [001] crystallographic direction; Bottom, an enlarged view of the region marked in the top panel. The inset shows the fast Fourier transformation (FFT) of the HR-TEM image. b TEM images and corresponding morphological models of one CuNC along two crystallographic directions, [001] and [111], from left to right. c, d TEM image of one CuNC electrolyzed for c 1 h and d 3 h. The arrows point to the positions where the degradations take place. e Tomographic reconstruction of the CuNCs and f corresponding schematic morphological models at different stages during a 12 h-course of CO2RR. Scale bars: 10 nm
