Synthesis, Characterization and Mechanism of MnFe2O4@g-C3N4 Nanocomposite as an effective Photocatalyst for the Generation of Hydrogen and organic contamination degradation

Abstract

Photocatalysis has recently been shown to be a good way to get rid of pollutants and produce hydrogen. MnFe₂O₄@g-C₃N₄ was synthesized by solid state synthesis technique. In addition to producing hydrogen, MnFe₂O₄@g-C₃N₄ demonstrated outstanding photocatalytic performance for the decay of pesticides under visible illumination. The morphology and structure of MnFe₂O₄@g-C₃N₄ were approved using Scanning Electron Microscopes (SEM), X-ray diffraction (XRD). Morover, Fourier transform infrared spectroscopy (FT-IR), UV–vis DRS, and surface area (BET). Based on the degradation of the carbaryl contaminant, the photocatalytic action of MnFe₂O₄@g-C₃N₄ was evaluated (94%). We for the first time could generate hydrogen by MnFe₂O₄@g-C₃N₄ and develop its photocatalytic activities by expanding the surface area and narrowing the band gap value (1.7 eV) and a great surface area of 53.46 m²/g, as displayed by the outcomes.
