Direct Z-Scheme CoFe2O4-Loaded g-C3N4 Photocatalyst with High Degradation Efficiency of Methylene Blue under Visible-Light Irradiation

Magnetically recyclable direct Z-scheme CoFe2O4-loaded g-C3N4 photocatalyst material was fabricated using a facile hydrothermal technique and subsequently characterized by XRD, VSM, PL, FT-IR, EDX, DRS, SEM, BET techniques. The characterization results confirmed that nanoparticles of CoFe2O4 are loaded on the surface sheets. optical band gap has been decreased from 2.65 eV to 1.30 means loading onto nanosheets g-C3N4. This enhanced separation process electron-hole. Under visible light irradiation, photocatalytic activity developed evaluated for photodegradation methylene blue (MB); during this MB decomposed up 98.86% in 140 min. Meanwhile, under same irradiation time conditions, themselves degraded 74.92% 51.53%, respectively. recovered solution after an external magnet studied determine its stability. It shown photoactivity did not change significantly five consecutive cycles.
