Investigation of the Effect of Surfactant on Dip-Coating TiO2 Photocatalyst

Abstract

Titanium oxide film obtained by dip-coating technique and its application as photocatalyst for dye (Methyl orange) and surfactant (Triton X100) are reported. The effect of the addition of Triton X100 on the photocatalytic properties of films has been studied and discussed. The films were investigated by XRD (structure), AFM (morphology), and photocatalytic properties. The surfactant affects the packing density (crystallite aggregation) during deposition improving the photodegradation efficiency. The photocatalytic degradation of Triton X100 is higher than the photocatalytic degradation of Methyl orange (0.0125 mM) due to the affinity to the substrate.
