In this research, the optical and visible-light-driven photocatalytic performance of Fe, Zn codoped-SrTiO3 nanotubes for the degradation of Basic Blue 41 (BB41) dye has been investigated. For this purpose, the nanotubes were synthesized by the liquid phase deposition (LPD) process by using the porous alumina templates, and then characterized using XRD, FE-SEM, EDS and UV-vis spectroscopy techniques. The FE-SEM and XRD analysis exhibited the SrTiO3 nanotube arrays with a perovskite structure and an average diameter of 100 nm was formed. Also, the optical properties of the synthesized samples indicated the optical absorption edge was found to be ≤400 nm and the optical band gap energy in the range of 2.65 to 3.12 eV. The photocatalytic results show that the Fe, Zn co-doping in the SrTiO3 structure significantly enhances the photocatalytic degradation of the BB41. This sample is able degradation of 91.4% BB41 under 80 min of irradiation with a rate constant of 0.032 min-1, which is 4 and 10 times higher than that of pristine SrTiO3 nanotubes, respectively.
