Morphological evolution of the CuNCs during electrolysis. a–c Representative CuNCs of three different sizes: a 16 nm, b 41 nm, and c 65 nm, imaged with TEM at different operation times. The rectangle in a encloses an aggregated assembly of particles. The red and yellow arrows in b indicate small clusters and broken CuNCs, respectively. Scale bars: 100 nm
