Figure 9

Photocatalytic degradation of Rh-B under visible light (solar simulator: 350 W Xenon lamp with a cutoff filter) with different conditions: (a) self degradation, (b) over pure TiO2, (c) over Nd-doped TiO2 with Ti : Nd = 23 : 1, (d) over Nd-doped TiO2 with Ti : Nd = 11 : 1, (e) over Nd-doped TiO2 with Ti : Nd = 6 : 1, and (f) over P25.
