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.

“…Ferrocene (Fc) is an organic transition metal compound that is widely used in various fields because of its excellent reversible redox properties. , Fc and its derivatives can not only be used to label proteins or aptamers in the construction of sensors but can also act as catalysts to catalyze and amplify signals. − In ECL, Fc is usually modified as the signal-quenching factor to change the signal to detect the target. − However, as far as we know, its catalytic properties have not been applied in ECL yet. Recently, we found that Fc(COOH) 2 can self-assemble into electroactive ferrocene derivative polymer nanospheres in methanol under natural sunlight, which can be utilized as a good electrochemical sensing platform .…”

Development of nanoluminophores with high efficiency, good stability, and excellent electronic transfer ability is one of the key challenges in electrochemiluminescence (ECL). Here, a porphyrin-based nanomaterial named Fc-TCPP was synthesized by self-assembly of 1,1′-ferrocenedicarboxylic acid (Fc(COOH)2) and tetrakis-(4-carboxyphenyl) porphyrin (TCPP) under infrared heating light. By tuning the ratio of the precursors, the morphology of Fc-TCPP can be regulated from primitive nanospheres to thorn-ball flowers decorated with branches and particles, and the possible formation mechanism was proposed. Nano-boron carbide (B4C) with carbon defect sites further boosts the ECL performance of Fc-TCPP, and thereby, an ECL biosensor for AFP was constructed innovatively. This study provides a simple and effective strategy for the preparation of ECL nanoluminophores taking the advantages of ferrocene and TCPP, opening a new horizon to design porphyrin-based nanomaterials with various structures and expanding their application in biosensing and disease diagnosis.
