Metal Nanoparticles on Semiconductor Surfaces: Electrochemistry and Photocatalysis

Fig. 6.1. Size distribution of Ag particles on thin-film Ti02 electrode. The particles were deposited under the treatment of Ti02 electrode with 0.001 M Ag2S04 for 1 min (a, b) and 10 min (c, d). The concentration of ionized donors in Ti02 (Nd) is equal to 10

19 cm"3 (a, c) and 1018 cm"3 (b, d).
