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 presence of common peaks at 2_: 25.34o - 75.00o corresponded to TiO2 anatase phase. FTIR and BET analyses also confirmed the formation of MTN and successful incorporation of Fe and gC3N4 into the hybrid catalysts. UV-DRS and PL results showed the extending of light absorption towards visible light region and lower rate of electronhole recombination was reached by the addition of Fe and gC3N4. The results displayed 5FeMTN-6/5gC3N4 owned the highest DBT photodegradation with 38.2% compared to the other photocatalysts. At the optimized conditions, 5FeMTN- 6/5gC3N4 reached 57.0% at 40 mg/L DBT concentration with 1 g/L photocatalyst dose and 0.01 mL H2O2. The presence of Fe and gC3N4 enhanced the photocatalytic performance by forming a heterojunction that promoted the generation and inhibit the electron-hole recombination. In conclusion, Fe and gC3N4 were successfully incorporate into MTN and reached 57.0% DBT photodegradation at optimized conditions. The implication of this study is this photocatalyst has good potential to be further investigated as a low-cost alternative for DBT removal in fuels.</p> 2024 thesis https://ir.upsi.edu.my/detailsg.php?det=13273 https://ir.upsi.edu.my/detailsg.php?det=13273 text eng N/A openAccess Masters Perpustakaan Tuanku Bainun Fakulti Sains dan Matematik <p class="MsoBodyText" style="text-align: justify; text-indent: -36.0pt; margin: 0cm 17.65pt .0001pt 54.0pt;"><span lang="EN-US">Aazam, E.
