Enhanced photocatalytic activity of SnO 2 @g-C 3 N 4 heterojunctions for methylene blue and bisphenol-A degradation: effect of interface structure and porous nature
AI summary Read the abstract
Researchers synthesized SnO2 and graphitic carbon nitride heterojunctions that achieved near-complete photocatalytic degradation of methylene blue (97%) and bisphenol A (99%) under sunlight within 60 minutes, with enhanced performance attributed to improved charge separation and increased light absorption at the porous material interface.
In this study, SnO2@graphitic carbon nitride (g-C3N4) heterojunctions were synthesized using a hydrothermal method followed by sonication. The catalytic efficiency of SnO2@g-C3N4 under sunlight was evaluated for methylene blue (MB) and bisphenol A (BPA) degradation. Characterization techniques, including X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and high-resolution transmission electron microscopy (HRTEM), confirmed the successful formation of SnO2 nanoparticles on g-C3N4 (GCN) sheets with porous morphology. The SnO2@GCN heterojunction achieved a 97% degradation efficiency for MB in 45 minutes, outperforming pure SnO2 (65.3%) and g-C3N4 (73.8%). Thus, the increase in photocatalytic activity is due to an enhancement in charge separation and an increase in the absorption of sunlight. For BPA degradation, the 5.0% SnO2@GCN composite demonstrated approximately 99% efficiency within 60 minutes. Additionally, recyclability tests showed good stability after five cycles, with no significant structural changes confirmed by FTIR and FESEM analyses. This study highlights the importance of interface structure and porous morphology in enhancing photocatalytic efficiency, paving the way for effective photocatalysts for wastewater treatment applications.
