Fabrication of hybrid covalent triazine framework-zinc ferrite spinel to uplift visible light–driven photocatalytic organic pollutant degradation

The tunability of porous covalent triazine frameworks (CTFs) can mitigate poor photostability and rapid hole-electron recombination. Herein, an excellent improvement of visible light–driven photocatalytic pollutant degradation was achieved using a hybrid semiconductor of covalent triazine framework-zinc ferrite spinel catalysts (CTF-ZnFe 2 O 4 ). The as-prepared CTF-ZnFe 2 O 4 composites were fabricated using a facile one-pot ionothermal method. The hybrid photocatalysts were identified using X-ray diffraction (XRD), scanning electron microscopy/energy-dispersive X-ray (SEM–EDX), X-ray photoelectron spectrometer (XPS), Brunauer–Emmett–Teller (BET), Fourier transform infrared (FTIR), and UV–visible diffuse reflection spectroscopy (UV–vis DRS) characterizations. The analysis reveals that hybridization successfully ensued and altered the crystallinity structure, morphology, surface area, and bandgap energy of hybrid material. It was found that CTF-ZnFe 2 O 4 90:10 is very effective for the degradation of MB in a UV–vis light photocatalytic process with the efficiency of 95.4
