One-Step Synthesis of Copper and Cupric Oxide Particles from the Liquid Phase by X-Ray Radiolysis Using Synchrotron Radiation

Figure 3

In the inset of (a), three red squared frames (i), (ii), and (iii) on the high-resolution SEM image of the particle depict the EDX measurement positions. EDX spectra measured from the positions (i), (ii), and (iii) are shown in (a), (b), and (c), respectively. The position (ii) corresponds to the surface of the core particle, while the positions (i) and (iii) are the surfaces of attached particles.
