Figure 5
SEM images of CuO particles synthesized by X-ray irradiation using a synchrotron source; different ratios of ethanol to an aqueous Cu(CH3COO)2 solution were used: (a) 3000:1, (b) 2000:1, (c) 20:1 and (d) 2:1. The corresponding ratios described in molar concentration are Cu(CH3COO)2:ethanol = (a) 0.37:5.72 × 10−3, (b) 0.37:8.17 × 10−3, (c) 0.37:8.17 × 10−2 and (d) 0.36 M:8.17 × 10−1 M. |
