Plots of photocatalytic degradation of RhB using 3D TiO2structures. Structures synthesized with various acid conditions: 0.68 M HCl, 0.90 M HCl, 1.12 M HCl, 1.35 M HCl, 0.90 HNO3, and 0.90 M HAc, respectively. The plot ‘without illumination’ represents the typical plot of photocatalytic degradation of RhB without illumination of the TiO2/RhB solution for TiO2 sample prepared with 0.68 M HCl since all the samples show almost the same plot without illumination.
