Abstract

Construction of a Z-scheme-based photocatalyst, i.e., NiFe2O4@P–g-C3N4 nanocomposite, was successfully fabricated by coupling phosphorus-doped g-C3N4 with spinel structure NiFe2O4. The structural, morphological, and spectroscopic data of the as-synthesized photocatalyst was successfully characterized through XRD, FTIR, SEM, TEM, UV-Vis DRS, PL, and XPS techniques. It was found that NiFe2O4@P–g-C3N4 had an increased light-absorption capacity, high exciton separation, low photogenerated electron–hole recombination, and showed better photocatalytic activity toward phenol oxidation and hydrogen energy production than the neat materials. Photocatalytic phenol oxidation by 20 wt% NFO@P–CN was also superior and could achieve a 96% conversion, which was 2 and 3 times higher than that by P–CN and NFO, respectively. The 20 wt% NFO@P–CN showed excellent photostability and was able to evolve 904 μmol h−1 H2 under visible-light irradiation. The enhanced photocatalytic activity of NiFe2O4@P–g-C3N4 was in good agreement with the photocurrent results. The synergistic effect between P–CN and NFO could accelerate photogenerated charge separation and, moreover, the distinctive magnetism of NiFe2O4@P–g-C3N4 aided the collection and recycling of the photocatalyst.
