Synthesis of La-doped ZrO2/g-C3N4 nanocomposite for eosin yellow photodegradation: A combined experimental and theoretical studies

In this study, La-doped ZrO₂/g-C₃N₄ nanocomposites were synthesized and remarkably, 0.8% La-doped ZrO₂/g-C₃N₄ exhibited an outstanding degradation efficiency of 87% (k = 11.301 × 10⁻³ min⁻¹). The enhanced photocatalytic performance is due to the synergistic effects of lanthanum and g-C₃N₄, which promote charge separation and increase the number of active sites. A built-in electric field exists according to the charge density difference and electrostatic potential results. At 300 K, the nanocomposite is thermally, energetically, and dynamically stable. Our results provide valuable insights into the design and development of efficient photocatalysts for the removal of organic contaminants from aqueous environments.
