Photocatalytic Degradation of Color and Protein Using Nitrogen-Doped Tio۲ Nanoparticles Under Visible Light Irradiation

The photocatalytic activity of titania (TiO۲) nanoparticles was improved using nitrogen as a dopantand urea as a nitrogen source. It was validated using Fourier-transform infrared spectroscopy (FT-IR),aiming to apply (in the future) in the polymeric structure of PVDF/MWCNT ultrafiltration membranes.Congo red (CR), methylene blue (MB), and bovine serum albumin (BSA) were selected as modelmembrane foulants to perform photocatalytic degradation studies using nitrogen-doped TiO۲ (N-TiO۲),where a maximum of ۴۶% degradation in pH=۱۲ was achieved for MB. Also, ۳۷% and ۷% degradationhave resulted in neutral pH for CR and BSA, respectively
