The limited access to fresh water and the increased presence of emergent pollutants (EPs) in wastewater has interest developing strategies for remediation, including photocatalysis. Graphitic carbon nitride (g-C3N4) is a 2D non-metal material with outstanding properties, such as 2.7 eV bandgap physicochemical stability, making it promising photocatalyst. This work reports process obtaining high-surface-area (SA) g-C3N4 using thermal-exfoliation posterior effect Ag-nanoparticle loading over exfoliated surface. photocatalytic activity samples was evaluated through methylene blue (MB) degradation under visible-light radiation correlated its physical properties obtained by XRD, TEM, BET, UV–Vis analyses. Moreover, 74% MB achieved compared bulk counterpart (55%) 180 min. better performances (94% remotion) were registered at low Ag loading, 5 wt.% optimal value. Such an improvement attributed synergetic produced higher SA role nanoparticles preventing charge-recombination processes. Based on results, this provides simple efficient methodology obtain Ag/g-C3N4 photocatalysts enhanced performance that adequate remediation sunlight conditions.

A nanocomposite composed of α-Fe2O3/g-C3N4 is synthesized using a modified ultrasonication approach, which engineered robust interfacial contact in the system. Phase formation and morphological features are confirmed via XRD electron-microscopy techniques. XPS revealed native oxidation states elements chemisorption-mediated interactions This developed composite produced hydrogen at rate 1494 μmolg−1 h−1, around 6.6 times higher than g-C3N4 The observed enhancement attributed to Z-scheme configuration, leading suitable band edge alignments, charge separation extended lifetime carriers composite.

This study explored the effect of dual doping with iron (Fe) and nitrogen (N) into cerium oxide/ceria (CeO2) at different concentrations, specifically 5, 10, 15 mol %, using a sol–gel method. Structural, chemical environment, oxidation state analyses revealed that effectively influenced crystal structure, switchable states ions (Ce3+ ↔ Ce4+), dopant-mediated compensation charge imbalance created by defect structures. In line these observations, changes such as enhanced optical absorbance in extended wavelengths decreased recombination were confirmed through analyses. As result, dual-doped ceria demonstrated individual simultaneous degradation reduction rhodamine B chromium VI heavy metal under sunlight irradiation. Over 2.5 h, bare system degraded around 50% pollutants, while optimized (10 %) nearly 100% pollutants both sole mixed conditions. observed enhancement was attributed to shifting conduction valence bands more negative positive potentials, respectively, positioning potentials suitably for effective photoredox reactions. Furthermore, cyclic efficiency doped remained consistent across all 5 cycles, demonstrating stability post-characterization, making it promising scale-up applications.
