Revolutionizing photocatalytic water treatment: An in-depth exploration of g-C3N4 iron oxide and carbon-mediated upgrading for an optimal decontamination of Vltava river water

Popis výsledku v původním jazyce

Efficient water decontamination and bacterial eradication represent the core objectives of our study. Fresh water samples taken from the Vltava River were used in all experiments. The goal was achieved by synthesis of graphitic carbon nitride (g-C3N4) photocatalyst modified with a combination of carbon (C) and iron oxide (Fe3O4). Carbon and iron oxide nanoparticles with different loadings were incorporated within the g-C3N4 nano-sheets by the wet impregnation method. Heat treatment was applied in order to achieve photocatalyst and nanomaterials cohesion. Photocatalysts and their precursors were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), ultraviolet-visible spectroscopy (UV–vis), photoluminescence, and Raman spectroscopy. The metal and non-metal sample composed of 1 C- 1Fe3O4/g-C3N4 revealed the best catalytic performance by eradicating bacterial species (N/N0 = 99.9%) under 30 min of light irradiation. The photocatalyst also showed a good activity in methylene blue (MB) degradation (C/C0 = 92%) under 180 min of visible light. The high activity of the treated photocatalyst 1 C- 1Fe3O4/g-C3N4 was attributed to an improvement in electrochemical properties and was also attributed to the double synergic mechanism due to the concurrent presence of iron and carbon nanoparticles in the g- C3N4 sheets. Moreover, the photocatalyst maintained a steady 99.9% bacterial degradation efficiency for 3 consecutive runs, proving its reusability. This exceptional catalytic activity, coupled with its stability and non-toxic nature shows the transformative potential of our material in revolutionizing water purification technologies. Our research underscores a significant progress towards addressing contaminants and energy challenges, and holds promise for a new era of sustainable water treatment. © 2023 Elsevier B.V.
