“…For the C 1s region (Figure 3a), the XPS spectrum of g-C 3 N 4 displays two major peaks at 284.8 and 288.1 eV, which are consistent with the C−C/CC and N C−N bonds, respectively. 26,48 The same result is observed in the XPS spectrum of α-Fe 2 O 3 /g-C 3 N 4 , where two peaks are fitted and located at 284.8 and 288.2 eV. However, the appearance of the C−O peak at around 285.9 eV in the composite spectrum is ascribed to carbon contamination.…”

The residue of antibiotics in the water has led to increased antibioticresistant bacteria, harm to human health, and damage to health-beneficial healthy bacteria. An idea of constructing S-scheme α-Fe 2 O 3 /g-C 3 N 4 nanocomposites is studied toward a photocatalysis application for an efficient resolution of commercial antibiotics in wastewater. Outstanding S-scheme Fe 2 O 3 /g-C 3 N 4 nanocatalysts are synthesized by a straightforward method and could easily improve the recycling property, thanks to magnetic materials. Empirical results indicate that S-scheme Fe 2 O 3 /g-C 3 N 4 photocatalysts can degrade commercial cefalexin and amoxicillin (20 mg L −1 ) under visible light, with five and nine times higher performance than that of g-C 3 N 4 , respectively. Furthermore, the detailed evidence to propose S-scheme Fe 2 O 3 /g-C 3 N 4 heterojunctions and comparison of photocatalytic performance in antibiotic degradation have also been mentioned in this study.

From the environmental and economic points of view, substitute fuel production has become one of the biggest concerns over the past decades. This work presents two photocatalytic nanocomposites, which can be utilized to generate hydrogen, an alternative fuel source. Fe2O3 and Fe3O4 were supported on carbon nitride nanotubes (C3N4 NTs) via the impregnation method for hydrogen generation under visible-light irradiation. The photocatalytic activity of C3N4 NTs, Fe2O3/C3N4 NTs, and Fe3O4/C3N4 NTs for hydrogen generation was evaluated at various percentages of loaded Fe2O3 and Fe3O4. Fe3O4/C3N4 NTs with 3% mass content of Fe3O4 has been shown to yield the highest photocatalytic performance, 1.9-fold that of the bare C3N4 NTs, and also showed exceptional stability with almost no change after three runs. The improved activity of Fe3O4/C3N4 NTs compared to that of Fe2O3/C3N4 NTs could be credited to the higher usage of visible-light radiation and efficient electron–hole pair separation, which is supported by comprehensive characterization results, leading to a lower recombination rate. The possible mechanism of the composite was also elucidated.
