Fig. 2

a Schematic preparation of Cu5.4O USNPs. b TEM image of Cu5.4O USNPs. Inset is the statistical chart of particle size distribution. The cross-sectional area of each particle was measured by using ImageJ Software from the TEM images, with at least 500 particles counted per sample. c Hydrodynamic diameter distribution of the Cu5.4O USNPs. d X-ray diffraction (XRD) pattern of the Cu5.4O USNPs, the rhombus, and star symbols represent the characteristic peaks of Cu2O and Cu, respectively. e XAES spectra of the Cu5.4O USNPs. Source data are provided as a Source Data file.
