Figure 4
(a) UV-Vis absorbance spectra of as-prepared photocatalyst [133]. (b) UV-Vis absorption spectra of ZnO nanospheres and ZnO nanoparticle films. (c) UV-Vis absorption spectra of the ITO/ZnO electrode dipped in the reaction solution for different times [148]. (d) UV-Vis absorption spectra of ZnO, the ZnO-CdS core-shell nanorods ((ZnO)1-(CdS)x, , 0.2, 0.3, 0.4, 0.5, and 0.6, are denoted as 101, 102, 103, 104, 105, and 106, resp.), and CdS [150]. (e) ZnO/CdS electron transfer process. (f) ZnO precursor. (Inset: the bandgap of ZnO/CdS nanoheterostructure is estimated from the absorption edge [155].)
