Figure 3From: Hydrothermal growth of TiO2 nanowire membranes sensitized with CdS quantum dots for the enhancement of photocatalytic performanceUV-vis absorption spectra of TiO 2 and CdS(2,4,6)-TiO 2 NWs and their band gaps. (a) UV-vis absorption spectra of TiO2 NWs and CdS(2,4,6)-TiO2 NWs. The bandgap of the samples synthesized by different S-CBD cycles: (b) 2 times, (c) 2 times, (d) 4 times, and (e) 6 times.Back to article page
