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 deeply characterized. 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. 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.
