In this study, a novel approach is introduced involving grafting and dip coating on photocatalytic substrates to create a Z-Scheme structure of TiO2@g-C3N4 (TC). The synthesized photocatalyst undergoes comprehensive characterization through techniques such as XRD, SEM, XPS, FTIR, Contact Angle Goniometer, and BET analysis. Two configurations, TC coated on PVDF membrane (TC-PVDF) and TC coated on Film (TC-Film), are evaluated for the photodegradation of NOx under visible light. Compared to the benchmark material TiO2, TC-PVDF nanoparticles demonstrate outstanding performance, boasting a specific surface area of 60.93 m²/g and minimal toxic NO2 byproducts, with concentration as low as 3.54 ppb, constituting only 0.46% during NOx remediation. These nanoparticles exhibit remarkable stability, with less than a 10% decrease in efficiency after 5 cycles of visible light irradiation. Plasma treatment transforms TC-PVDF from superhydrophobic to hydrophilic, with a contact angle reduction from 124.7° to 0°. Notably, TC-PVDF shows substantial efficiency enhancements, reaching 84.04%. This study broadens insights into catalytic bag filters, providing practical implications for their use in NOx removal. It offers innovative solutions for air purification, addressing environmental challenges and advancing sustainable technologies. [ABSTRACT FROM AUTHOR] |
