Abstract
SrTiO3/g-C3N4 mesostructured heterojunctions were synthesized using hydrothermal method with different weight percentages of SrTiO3 (ST) in carbon nitride (CN). The samples are named as CN-ST05, CN-ST10, CN-ST15, CN-ST20, and CN-ST25 based on 5, 10, 15, 20 and 25 wt% of ST respectively in CN. The surface area of the heterojunctions ranged between 33.7 to 63.4 m2/gm. The optical, structural, and elemental properties of the heterojunctions were evaluated. Finally, the photocatalytic tests confirmed that CN-ST15 showed 97% degradation of methylene blue (MB) after 4 h of visible light irradiation, (the bare CN and ST showed 70% and 34% degradation respectively). The photocatalytic activity for methylene blue degradation followed the trend: CN-ST15 > CN-ST10 ≈ CN-ST20 > CN-ST25 > CN-ST05 > CN > ST.
