Abstract:
Fe- and Cr-doped titania nanotubes were prepared by hydrothermal treatment. After the calcination process, pure TNTs gave the best photocatalytic activity, comparing to M-loaded TNTs. The prepared catalysts were characterized by XRD, TEM, BET, and XRF. The photocatalytic activity of catalysts were evaluated though the photodegradation of methyl orange. When compared to the metal-loaded TNTs, the pure TNTs resulted in photocatalytic activity while the best optimum dopant amount of Fe found to be at 2% and 15% Cr-doped TNTs calcined at 500 °C possessed the best absorption in dark.
