| Summary: | Titanium dioxide (TiO2) has been acknowledged as a promising photocatalyst in environmental remediation
including wastewater treatment. In this study, TiO2 nanoparticles either by single or co-doped of iron (Fe) and nitrogen (N)
via sol-gel method and calcined at 500 °C for 3 hours. This experiment investigated the performance of mono/co-dopant
of TiO2 photocatalyst against methyl orange in aqueous solution under UV light irradiation. The experimental results
showed the rate of degradation favored in co-doped TiO2 followed by mono doped TiO2 and pristine TiO2. The
photocatalytic reaction followed pseudo first-order kinetics which were rationalized in terms of the Langmuir–
Hinshelwood model and provided nearly complete degradation |
