This study aimed to incorporate Fe and gC3N4 into Mesoporous Titania Nanoparticles (MTN) and investigate photodegradation of Dibenzothiophene (DBT). MTN with various aging time (x = 2, 4, 6 and 8 days) were synthesized via sol-gel method before being incorporated with 5wt% Fe (5Fe/MTN-x) and 5wt% gC3N4 (5FeMTNx/ 5gC3N4) using wet-impregnation method. The photocatalysts were characterized using X-ray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FESEM) with EDX analysis, UV-Visible Diffuse Reflectance Spectroscopy (UVDRS), Fourier-Transform Infrared Spectroscopy (FTIR), Surface Area Analysis (BET), Photoluminescence Spectroscopy (PL) and Raman Spectroscopy. Photocatalytic performance was evaluated through DBT photodegradation under ultraviolet (UV) light irradiation for 180 min. Parameters such as H2O2 volume, DBT concentration and photocatalyst dose were manipulated with prolonging the reaction time to 240 min. The results of XRD showed the formation of MTN with the p.....
