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

Figure 2

(a) SEM image of a well-patterned CuSO₄ solution with ethanol (solution #3) after X-ray irradiation for 5 min. The dashed circle and arrows correspond to the slit patterned areas. (b) Magnified SEM image of Cu particles nucleated from the mixed solution under X-ray irradiation. ((c) and (d)) High-resolution SEM images of the nucleated particles. The arrow in (c) points out a cuboctahedral like particle.
