ZnO Modified g‐C₃N₄–MnO₂ Composite for Photodegradation of Methylene Blue

ChemistrySelect, Год журнала: 2025, Номер 10(1)

Опубликована: Янв. 1, 2025

Abstract Single ZnO (NM1), MnO 2 (NM2) nanoparticles, and –g‐C 3 N 4 –ZnO (NM4) nanocomposite were synthesized by the sol–gel method, whereas g‐C (NM3) was polymerization of urea. The as‐synthesized materials characterized thermogravimetric‐differential thermal (TGA‐TDA), Fourier transformer (FTIR), X‐ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), high‐resolution transmission (HRTEM).The bandgap NM4 lower than those NM1, NM2, NM3 photocatalysts, which is applicable in visible region. photocatalytic activities studied under light radiation. efficacy composite 5, 3.4, 3‐fold higher materials. This enhancement might be ascribed to synergistic effect. Besides, degraded 94% methylene blue (MB) 81% real sample. rate constant ( k ) for NM3, also resulted 0.00327, 0.0046, 0.0056, 0.0156 min −1 , respectively. reusing carried out four sequential rounds 94%, 92.6%, 91%, 89% degradation efficiency 1st, 2nd, 3rd, 4th round, result suggests that cost‐effective stable.

Synthesis and photocatalytic degradation efficiency of MgFe₂O₄@CuO nanocomposite for Bromophenol blue dye removal

Journal of the Chinese Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Март 14, 2025

Abstract Rapid advances in science and technology have made life easier, but they also brought forth a number of issues that put both living things non‐living objects at risk. In this work, MgFe 2 O 4 @CuO has been synthesized via the co‐precipitation method to minimize creation environmentally unfavorable gases, demonstrating need for materials may be used purposes. Particularly, nanocomposite aims removal Bromophenol blue (BPB) dye. Utilizing FTIR, XRD, EDX SEM, as‐synthesized material was examined. Therefore, parameters, including contact duration, pH activity, etc., were thoroughly examined order measure effectiveness photocatalytic degradation. The degradation efficiency composite is noticed 52.68%, 66.65%, 90.94% 15, 30, 45 min, respectively. Of all samples, heterojunction exhibits highest efficiency. According results, magnetic ferrite enhances charge transfer, decreases electron–hole recombination, increases radiation absorption. Results work exhibit industrial wastewater treatment. As result, affordable useful variety tasks.
