Photocatalysis data and analysis.
(a) ln(C/C0) versus time curves under UV-visible irradiation acquired from the TiO2/Al films at 40 V, 60 V, 80 V, 100 V and flat TiO2/Al film without nano-voids and with no film. (b) Corresponding photocatalytic rate versus the TiO2/Al film fabrication voltage/nano-void diameter scale.
